Cheap Fuel Cells, A Very Real Possibility


Researchers at Los Alamos National Laboratory have developed a platinum-free catalyst in the cathode of a hydrogen fuel cell that uses carbon, iron and cobalt. This could significantly lower the cost of fuel cells in general. Up to this point hydrogen fuel cells used platinum, lots of it. And as you know, the metal is rare and frightfully expensive (according to the Wired article, Platinum goes for $1800 an ounce! ouch!). The price of platinum alone will put the cost of even a modest car at around $50,000.

Hydrogen fuel cells offer all the benefits of an electric vehicle without the drawbacks, mainly that of short range and long recharge times.

Conventional hydrogen fuel cells us the platinum as a catalyst. The new design uses a carbon-iron-cobalt catalyst to complete the conversion of hydrogen and oxygen into water. The other good news is that the carbon based fuel cell is on par for durability with it's platinum counterpart.

The team at Los Alamos National Laboratory are hesitant to quantify just how much cheaper the new fuel cell would be, not because they fear that they have over estimated the saving, but under-estimated it. Platinum is likely to become much more expensive after car manufacturers start installing platinum based cell in 2015, but since the elements for the new catalyst are readily available, it is likely that it will vastly lower the price.
