Low-cost iron catalyst can make hydrogen fuel cells affordable

Iron-based catalysts are less costly alternatives because iron is abundant and inexpensive. But it does not perform as well as platinum, especially because it lacks the durability to withstand the highly corrosive and oxidative environments inside fuel cells. To overcome this barrier, the researchers bonded four nitrogen atoms to the iron.
