MEMBRANE-ELECTRODE ASSEMBLY FOR FUEL CELL, FUEL CELL AND MANUFACTURING METHOD THEREOF

摘要

PURPOSE: A membrane-electrode assembly for fuel cell is provided to minimize the contact surface resistance of interfaces by closely contacting, and to minimize loss and resistance at current collecting. CONSTITUTION: A membrane-electrode assembly for fuel cell comprises: electrolyte layers(11a,11b) consisting of two electrolyte solutions which surface-contacting each other; catalyst layers(12a,12b) on the both sides of the electrolyte layers; microporous layers(13a,13b) on the both sides of the catalyst layer; micro current collecting layers(14a,14b) on the both sides of the microporous layers; and gas diffusion layers(15a,15b) on the both sides of the micro current collecting layers. The micro current collecting layers are comprises Au, Ag, Cu, Al, Fe, alloys thereof, or combinations thereof. The micro current collecting layers have mesh structure.
