Cobalt may beat platinum for cheap fuel cells
A new, inexpensive catalyst for hydrogen fuel cells could put platinum out of business, say researchers who’ve developed an alternative out of cobalt, graphene, and cobalt-oxide.
The new material “has the best reduction performance of any nonplatinum catalyst,” says Shaojun Guo, a chemisty postdoc at Brown University.
The team are optimistic that with more study their material could one day be a suitable replacement for platinum catalysts. “Right now, it’s comparable to platinum in an alkaline medium,” Sun says, “but it’s not ready for use yet. We still need to do more tests.”
