| abstract | The present invention provides a catalyst for a low temperature fuel cell having a metal catalyst supported on a porous catalyst carrier modified to have ionic conductivity, a method for manufacturing the same, an electrode for a low temperature fuel cell using the catalyst, a method for manufacturing the same, and a membrane electrode assembly for a low temperature fuel cell using the catalyst. The present invention relates to a low temperature fuel cell using the catalyst, and a method of manufacturing the same. According to the present invention, the metal catalyst is prevented from entering the micropores of the catalyst carrier and the amount of the metal catalyst in contact with the ion conductive polymer electrolyte material in the electrode is increased so that the reactant, the catalyst and the ion conductive polymer electrolyte material in the electrode catalyst layer are increased. By increasing the area of the three-phase interface to meet the active hydrogen ion transfer, it is possible to dramatically increase the utilization of the metal catalyst. In addition, according to the present invention, it is possible to improve the performance of the fuel cell by reducing the electrical resistance and by reducing the overpotential of the electrode by reducing the amount of the ion conductive polymer electrolyte material added during electrode production. The catalyst prepared according to the present invention is used as a catalyst for low-temperature fuel cell electrodes, low-temperature fuel cell membrane electrode assemblies, and low-temperature fuel cells as a source of pollution-free energy, which can bring about improved performance of low-temperature fuel cells, and by reducing the amount of catalyst used. The cost of the low temperature fuel cell stack can be greatly reduced.n n n n Low temperature fuel cell, fuel cell catalyst, modified porous carrier, ion conductive polymer electrolyte, three phase interface, catalyst utilization |
