DOE progresses towards cheaper fuel cells

Scientists at the US Department of Energy’s (DOE) Argonne National Laboratory have developed platinum-free fuel cell catalysts that can be used for cheaper hydrogen fuel cell production.

Commercially available hydrogen fuel cells currently rely on the oxygen reduction reaction (ORR), which splits oxygen molecules into oxygen ions and combines then with protons to form water.

The reaction is part of the overall fuel cell process that coverts hydrogen and oxygen in air into water and electricity. The ORR is a relatively slow reaction, limiting fuel cell efficiency and requiring a large amount of platinum catalyst.
