Abstract

Finding nonnoble metal catalysts for electrodes in fuel cells is an important subject of recent study. In this study, a new polythiophene derivative bearing the porphyrin, cobalt 5-(3-thienyl)-10,15,20-triethyl-21H, 23H-porphine, was synthesized by electropolymerization onto the surface of carbon particles. The modified carbon particles were suspended in an alcoholic solution of Nafion, and a pseudo-MEA was prepared on an electrode by casting the solution. The catalyst showed highly efficient catalytic activity for the selective four electron reduction of oxygen at E_1/2 = 0.57 V vs SCE by rotating ring-disk voltammetry.
