PURPOSE: A membrane-electrode assembly for a fuel cell is provided to improve a current-voltage performance of a fuel cell stack and to prevent the degradation of durability of a fuel cell stack caused by the shortage of fuel supply. CONSTITUTION: A membrane-electrode assembly(100) for a fuel cell comprises: anode and cathode electrode layers(30,40) formed at both sides of the membrane(20); and anode and cathode gas diffusion layers(50,60) formed at the anode electrode layer and the cathode electrode layer. The anode gas diffusion layer is thickly formed than the cathode gas diffusion layer by 5% or more to prevent flooding phenomenon. |
