A ONE BODY TYPE MEMBRANE ELECTRODE ASSEMBLY WITH GASKET OF MULTIPLE SEALING STRUCTURE FOR A FUEL CELL |
摘要 |
A membrane-electrode assembly formed integrally to a gasket having a multiple sealing structure for a fuel cell is provided to improve the assemblage rate, to minimize contamination of a membrane-electrode assembly caused by leakage of an anti-freezing agent, and to increase the interfacial adhesion between a membrane-electrode assembly and a gas diffusion layer. A membrane-electrode assembly(110) includes a polymer electrolyte membrane(112) having a reaction gas manifold and a cooling water manifold for sucking and discharging reaction gases and cooling water, and catalyst layers(114) of a cathode and an anode bonded to both surfaces of the polymer electrolyte membrane. The membrane-electrode assembly further comprises: a gas diffusion layer(120) bound to both surfaces of the membrane-electrode assembly for dispersing the reaction gases uniformly over the membrane-electrode assembly; and at least one gasket(130,140) formed integrally to the membrane-electrode assembly corresponding to the shape of the membrane-electrode assembly for preventing leakage of the cooling water. |
