Novel proton-conductive membranes for automobile fuel cells

Fuel cells are compact energy conversion units that utilize clean energy sources like hydrogen and convert them into electricity through a series of oxidation–reduction reactions. Specifically, proton exchange membrane ...

Economizing on iridium

Iridium is an ideal catalyst for the electrolytic production of hydrogen from water—but it is extremely expensive. But now a new kind of electrode made of highly porous material does an excellent job with just a hint of ...

Ammonia for fuel cells

Fuel cells are pollution-free power sources that convert chemical energy to electricity with high efficiency and zero emissions. Fuel cell cars, trucks, and buses would allow people to travel long distances with convenient ...
