Pt/Rh/Fe alloy catalyst for fuel cells and a process for producing the same

摘要

A platinum alloy catalyst on an electrically conductive carbon support which contains an alloy of 40 to 60 atom-% of platinum, 10 to 20 atom-% of rhodium and 20 to 50 atom-% of iron in the form of finely divided alloy particles. The catalyst is characterised in that the average particle size of the alloy particles is less than 10 nm.
