ANION-EXCHANGE MEMBRANE FUEL CELLS

Addressing a basic issue

Subjects

Anion-exchange membrane fuel cells (AEMFCs) potentially allow the use of cheap catalysts due to their alkaline environment, yet often large amounts of precious metals are employed. Now, a non-precious metal-based catalyst, specifically designed for alkaline media, is demonstrated in the cathode of a high-performing AEMFC.
