Fuel cells have long held promise as power sources, but low efficiency has created obstacles to realizing that promise. Researchers have identified the active form of an iron-containing catalyst for the trickiest part of the process: reducing oxygen gas. The finding could help researchers refine better catalysts, making fuel cells a more energy- and cost-efficient option for powering vehicles and other applications.
