When you think about precious metals, what elements come to mind? To be
sure, gold, silver, and platinum come to the forefront. What about
palladium? It is a precious metal, a platinum group metal, and a noble
metal. Palladium was discovered by the British chemist William Hyde
Wollaston in 1803. He named this precious metal, in 1804, after
"Pallas" the ancient Greek goddess of wisdom whose name had
also recently been given to the second asteroid ever discovered. Few
people have heard of this precious metal in spite of its myriad uses, a
couple of headline-grabbing stories, and what may be quite an
interesting future as to helping us break free of our petroleum-energy
dependence – perhaps even interesting enough to buy a few ounces for
your portfolio.
Palladium is
predominantly mined in Canada, Russia, South Africa, and the United
States (Montana). To give you an idea of how rare this metal is, about
6.8 million ounces of palladium were mined in 2004. This compares to
79.2 million ounces of gold and 620 million ounces of silver mined in
the same year. Platinum is slightly rarer with 6.4 million ounces
produced in 2004.
Before delving further
into palladium, I would be remiss not to mention a bullish contrarian
indicator as to why precious metals are in the early stages of a bull
market. As a surety bond underwriter, I analyze hundreds of personal
financial statements every year. Bar none, real estate is where most
people are "investing" their money. Equities (i.e. publicly
traded stocks) come in a distant second place. Cash and bonds, of
course, commonly occupy the asset side of a personal balance sheet as
well. When it comes to precious metals, however, this asset class is
completely off the radar screen. Maybe one in every two hundred personal
financial statements will list precious metals (mostly gold and silver)
as an asset. So when you hear the talking heads say "gold and
silver have had a nice run but the party is over" don’t believe
it. When the common man comes to realize that the Federal Reserve is
debasing the dollar at breakneck speed, he is going to jump into
precious metals with a vengeance. This is when the real fireworks will
begin. We’re not even close to this point yet and that’s why I’m
bullish on precious metals.
Palladium’s Uses
Much like silver,
palladium is a precious metal whose demand is derived chiefly from
industrial users. It is a versatile metal, which is ductile and is
resistant to both oxidation and high temperature corrosion. Here is a
list of notable applications:
-
Automobile
Catalytic Converters: Palladium is used as a primary component
in autocatalysts that reduce vehicle exhausts emissions of
hydro-carbons, carbon monoxide, oxides of nitrogen, and particulate.
Autocatalysts convert most of these emissions into less harmful
carbon dioxide, nitrogen, and water vapor.
-
Dentistry:
Palladium-based alloys are used in dentistry for dental crowns and
bridges. This noble metal is compatible with human tissue.
-
Jewelry:
Palladium is lighter than platinum having about the same density as
silver. In jewelry, it is principally used as an alloy with platinum
to optimize platinum’s working characteristics and wear
properties. However, due to platinum’s current high price,
palladium is gaining popularity as a primary metal in jewelry –
especially in China. It is also used as an alloy to make white gold.
-
Manufacturing
and refining: Palladium is an important part of the refining of
nitric acid, and plays a significant role in the production of
synthetic rubber and nylon. It is a critical catalyst in the
manufacture of polyester and serves important functions in catalytic
reactions that are used in various stages of petroleum refining.
-
Photography:
Palladium is used in an historic photographic printing process that
is considered to be superior to conventional silver in tonal quality
and archival longevity.
Headline-Grabbing
News
On March 23, 1989,
palladium became an integral part of headline news around the world. For
on this date, at a news conference, Stanley Pons and Martin Fleischmann
(both of the University of Utah) reported experimental results in which
energy was generated via a "cold fusion" process.
Thermonuclear reactions occur when temperatures are in the millions of
degrees Celsius. To bring about nuclear fusion, using a simple table-top
apparatus, was stunning news. Pons and Fleischmann’s apparatus
essentially consisted of an electrolysis cell containing heavy water (dideuterium
oxide) and a palladium cathode which rapidly absorbed the
deuterium produced during electrolysis. What Pons and Fleischmann found
was that the device’s energy output exceeded the energy input. In
other words, they had discovered a process to bring about nuclear fusion
at room temperature – or so they believed.
Palladium was the key
component in this experiment. Fleischmann and Pons hypothesized that
palladium may catalyze fusion due to this noble metal’s special
ability to absorb large quantities of hydrogen (including its deuterium
isotope). Similar experiments, conducted soon thereafter, produced
disappointing results. Hence, a Department of Energy panel concluded:
"Nuclear fusion at room temperature, of the type discussed in this
report, would be contrary to all understanding gained of nuclear
reactions in the last half century; it would require the invention of an
entirely new nuclear process."
Alas, palladium had its
day in the sun as a "miracle" metal that could safely bring us
nuclear energy at a very low cost. For those who still believe, keep in
mind that unexplained experimental results do not mean that Pons and
Fleischmann’s experiment was wrong. Superconductivity, after all, was
first observed in 1911 and explained theoretically decades later in
1957. There is mounting evidence
that Pons and Fleischmann were on to something big.
In January of 2002,
Ford Motor Company made business headlines by announcing a staggering
net loss of $5.5 billion for fiscal-year 2001. What is so startling here
pertains to the fact that $1 billion of this loss was related to Ford
Motor Company’s panic-buying of palladium – which, as mentioned
above, is used in automobile catalytic converters. Due to supply
problems emanating from Russia, the price of palladium spiked to over
$1,000 an ounce. Instead of switching back to using platinum as the
catalyst metal, Ford stockpiled massive amounts of palladium at
near-peak prices. As demand for palladium dropped and Russian supplies
began coming back onto the market, the price of palladium plunged to
about $400 an ounce. Ford Motor Company, consequently, had to mark down
the value of its palladium inventory by the aforementioned $1 billion;
thus writing another embarrassing chapter of American automotive
history.
Hydrogen Fuel Cells
and Palladium
A fuel cell operates
very much like a battery given that it produces power in the form of
electricity. Unlike a battery, it does not run down or need recharging
because it produces energy as long as fuel is supplied to it.
Hydrogen-rich fuels, that have been successfully utilized, include
biodiesel, diesel, ethanol, kerosene, methane, methanol, natural gas,
propane, and others. If fuel cell technology becomes commercially
viable, then the internal combustion engine will be replaced by fuel
cells and the global dependence on petroleum – as an energy source –
will diminish markedly.
So how does a fuel cell
work? Hydrogen fuel is fed into the anode of the fuel cell. Oxygen (or
air) enters the fuel cell through the cathode. Encouraged by a catalyst,
the hydrogen atom splits into a proton and an electron, which take
different paths to the cathode. The proton passes through the
electrolyte. The electrons create a separate current that can be
utilized before they return to the cathode, to be reunited with the
hydrogen and oxygen forming a molecule of water. Indeed, the main
emission from the fuel cell is water vapor (which, by the way, is
a greenhouse gas – this is something you won’t hear from
environmentalists).
Fuel cells perform best
when the hydrogen fuel is free of impurities. This is where palladium
shines. Using a palladium membrane hydrogen purifier, pressurized
hydrogen is diffused across the palladium membrane – keep in mind that
only hydrogen possesses the ability to diffuse through palladium.
As hydrogen passes through the palladium membrane, hydrogen loses its
electron to the palladium structure and diffuses through the membrane as
an ion (or proton). At the exit surface, the reverse process occurs.
Therefore, the process can be described as follows: (1) adsorption, (2)
dissociation, (3) ionization, (4) diffusion, (5) reassociation, (6)
desorption. Once the hydrogen gas passes through the palladium membrane,
an ultra-pure hydrogen gas may be fed into the fuel cell – thus
preventing the anode catalyst, in the fuel cell, from being poisoned by
trace impurities. There are fuel cell manufacturers using palladium for
this exact purpose.
Another possible use
for palladium, associated with hydrogen fuel cells, concerns hydrogen
storage. At room temperature and atmospheric pressure, palladium can
absorb up to 900 times of its own volume of hydrogen. One way to
envision this is to imagine a sponge soaking up hundreds of buckets of
water. From a safety standpoint, it may be more desirable to store
hydrogen in a palladium bed (at room temperature and atmospheric
pressure) than storing an equal volume of hydrogen in a highly
pressurized tank.
Fuel cell power systems
are already in use. They are being employed in hospitals, hotels,
nursing homes, office buildings, schools, utility power plants, and an
airport terminal – either providing primary or backup power. Likewise,
they are being used as primary and backup power sources in homes. It is
also quite exciting that DaimlerChrysler, Ford, General Motors, Honda,
Nissan, and Toyota each have working fuel cell powered cars. Optimists
claim that fuel cell powered cars might be commercially available by
2010.
Conclusion
As fuel cell technology
progresses, the day may come where we are weaned off of our petroleum
dependence. In turn, conceivably, a more peaceful world will emerge. And
with palladium’s future intertwined with the fuel cell, maybe we can
make a buck or two by purchasing a few ounces of this hard-working
precious metal. At $273 an ounce, palladium may be a bargain today.
For your information, I
do eat my own cooking. Here are pictures of one of my recent purchases.
