<P>PROBLEM TO BE SOLVED: To provide a method of manufacturing a fuel cell, easily producing a fuel cell of which durability and power generation performance can be improved. <P>SOLUTION: The method provides the fuel cell equipped with an MEA having an electrolyte film 1 and catalyst layers laid on both sides of the electrolyte film 1 and diffusion layers laid on the outside of the MEA. The lamination area of the catalyst layer is smaller than those of the electrolyte film 1 and the diffusion layer and an end part of the catalyst layer is tilted so as to be abuttable with the diffusion layer. The method includes a step of masking the end part with a frame-shaped masking member 20, and a step of making the catalyst layer after the masking step by spraying a catalyst component from the upside of the mask member 20 on the lamination area of the electrolyte film 1. The inner side of the masking member 20 is formed to be at an acute angle to the lamination area of the electrolyte film 1. <P>COPYRIGHT: (C)2007,JPO&INPIT |
