Japan’s Daihatsu Motor Co Ltd has just announced that it has developed a new technology that will enable them to make fuel cells without platinum. Platinum is the precious metal used in the electrolyte process in current hydrogen-based fuel cells.
By using alkali, instead of acid, anion exchange membranes, the new fuel cell can use much cheaper metals that are more also more corrosion resistant. The new fuel cell will also use hydrazine hydrate, which is a liquid industrial material, rather than hydrogen. Even with hydrazine hydrate instead of hydrogen, the fuel cell will still not emit any carbon dioxide.
