      다국어 초록 (Multilingual Abstract)

      The electrochemical characteristics of oxygen reduction of a porous electrode for phosphoric acid fuel cell have been studied. The best result for the manufacturing of fuel cell electrode was obtained when the amounts of PTFE contained in the catalytic layer and in the gas diffusion layer were 30% and 40%, respectively. The gas diffusion layer had the porosity of 60-65% and mean pore-diameter of 20-30㎛ when the foaming agent(ammonium bicarbonate) to the carbon black was 600wt%. The optimum amount of platinum catalyst impregnated in carbon black was 0.5㎎/㎠. At these conditions, cathode current density was 240㎃/㎠ at 0.7V(vs. NHE).
