| Abstract: | Cobalt tetrapenylporphyrin, as a kind of oxygen reaction catalysts used in proton exchange membrane fuel cells (PEMFC), was prepared with the unpurified tetrapenylporphyrin, Co(OH)_2 and carbon black. The influences of preparation conditions, such as the reactant components and temperature of the heat-treatment were studied. The electrocatalytic performances of prepared catalysts were evaluated by current-voltage curves of a single PEMFC and the cyclic voltammetry method. |
