A novel and improved fuel cell electrode includes a finely divided noble metal-base metal alloy catalyst. The catalytic activity of noble metal in the electrode is greater than the catalytic activity of the same unalloyed noble metal. Theoretically any base metal may be advantageously alloyed with the noble metal and will yield improved catalytic activity. Preferably the finely divided alloy is supported.
