PNNL Researchers Develop Iron-Based Fuel Cell Catalyst

Iron-based catalyst offers similar efficiency to that of current PEM-based catalysts based on platinum, but work needs to be done to speed up the process and determine its best working conditions.

Published: 19-Feb-2013

The creation of the first iron-based catalyst to converts hydrogen directly to electricity has moved affordable fuel cells one step closer.

Researchers at the Center for Molecular Electrocatalysis at the US Department of Energy's Pacific Northwest National Laboratory have outlined their discovery in the latest issue of Nature Chemistry.

"A drawback with today's fuel cells is that the platinum they use is more than a thousand times more expensive than iron," said chemist R. Morris Bullock, who leads the research.
