Performance of novel bimetallic carbonyl clusters as PEM fuel cell anodes, a comparative study

► Novel bimetallic carbonyl clusters as ORR catalysts. ► Novel bimetallic carbonyl clusters as HOR catalysts. ► RuxIry(CO)n, RuxRhy(CO)n and RhxIry(CO)n perform as anodes in an H2 fuel cell. ► Superior anode performance with H2/CO as fuel feed, compared to Pt. ► Potential use of these materials in reforming hydrogen PEMFCs.
