Influence of Heat Resistance of Precursor in Cathode Catalysts for Polymer Electrolyte Fuel Cell on Oxygen Reduction Activity
Several polyamide composites were obtained by condensation reaction of tetracarboxy cobalt phthalocyanine with several diamino-functionalized monomers. The obtained composites were pyrolyzed at 900 degrees C in a hydrogen stream to afford several platinum-alternative oxygen reduction catalysts for polymer electrolyte fuel cells containing different nitrogen contents and the oxygen reduction activity (ORA) was investigated. It was revealed that the ORA was related not to the nitrogen content but to the heat resistance of the precursors of the catalysts.
