PLATINUM ALLOY CARBON-SUPPORTED CATALYSTS

摘要

The instant invention relates to a platinum alloy supported electrocatalyst for gas diffusion electrode and/or in catalyst-coated membrane. The carbon-supported platinum alloy catalyst is obtained by simultaneous chemical reduction of in situ formed platinum dioxide and of at least one transition metal hydrous oxide on a carbon support. The transition metal is preferably selected from nickel, chromium, cobalt, vanadium and iron.
