Protonated iron-phthalocyanine complex used for cathode material of a hydrogen peroxide fuel cell operated under acidic conditions

An iron-phthalocyanine complex was utilized as a cathode for constructing a one-compartment hydrogen peroxide fuel cell operated under acidic conditions for the first time. The protonation to the phthalocyanine ligand is crucial to exhibit high activity toward hydrogen peroxide reduction. Nafion (R) coating of the anode improved the stability of the fuel cell.
