PURPOSE: A method for manufacturing a membrane electrode assembly for a fuel cell is provided to maintain excellent adhesive force between a hydrocarbon-based polymer electrolyte membrane and a catalyst layer and to improve the lifespan and operation stability of the fuel cell by preventing the separation of the electrolyte membrane and the electrode. CONSTITUTION: A method for manufacturing a membrane electrode assembly for a fuel cell comprises the following steps: forming catalyst layers(203,205) by spreading ink on a gas diffusion layer(208); forming hydrocarbon-based polymer layers(202,204) by spreading a hydrocarbon-based polymer solution on the catalyst layers; spreading a mixed solution of water and alcohol on the hydrocarbon-based polymer layer; and attaching outcomes on both sides of a hydrocarbon-based polymer electrolyte membrane(201) by spreading the hydrocarbon-based polymer solution on the catalyst layer. |
