HYDROGEN OXIDATION CATALYST

摘要

The present invention is to provide a hydrogen oxidation catalyst that does not contain platinum. Disclosed is a hydrogen oxidation catalyst that is a dinuclear transition metal complex having a chemical structure represented by the following general formula (1) or (2):
wherein, in the general formulae (1) and (2), M 1 and M 2 are each independently Fe or Ru; Ar 1 and Ar 2 are each independently a cyclopentadienyl group or a pentamethylcyclopentadienyl group; Ar 3 and Ar 4 are each independently a divalent aromatic hydrocarbon group having 6 to 12 carbon atoms; and Ar 5 is a monovalent aromatic hydrocarbon group having 6 to 12 carbon atoms, and in the general formula (2), R 1 and R 2 are each independently a hydrogen atom or a monovalent aliphatic hydrocarbon group having 1 to 3 carbon atoms.
