SOLID POLYMER FUEL CELL AND METHOD FOR PRODUCING MEA USED FOR SOLID POLYMER FUEL CELL |
摘要 |
This invention intends to improve the catalyst efficiency by sufficiently providing a triple phase boundary where reaction gas, catalysts, and electrolytes meet in carbon nanohorns. With the utilization of the resulting MEA, the electrode reactions are allowed to effectively proceed, and the power generation efficiency of a fuel cell is improved to result in a solid polymer fuel cell with excellent properties. Such solid polymer fuel cell comprises electrodes having a catalyst layer comprising: a carrier comprising a carbon nanohorn aggregate; catalytic metals supported on the carrier comprising a carbon nanohorn aggregate; and polymer electrolytes coating the carrier comprising a carbon nanohorn aggregate, wherein the proportion of the polymer electrolyte to the carbon nanohorn aggregate is 0.32:1 to 0.70:1 by weight. |
