A low-loading Ru-rich anode catalyst for high-power anion exchange membrane fuel cells.

Herein, we report a Ru-rich anode catalyst for alkaline exchange membrane fuel cells. The fuel cell with such a RuPdIr/C anode and Ag-based cathode attained a peak power density close to 1 W cm-2 with only 0.2 mg cm-2 anode precious group metal loading, reaching the highest mass activity reported for this technology.
