<P>PROBLEM TO BE SOLVED: To suppress degradation in electrode quality when an electrode is formed on the surface of an electrolyte membrane and simplify a manufacturing process by eliminating a process for providing a sealing material on an electrolyte membrane in an after-process. <P>SOLUTION: A masking film 13 having double-layer structure comprising a masking film body 9 and an anode gasket 3 is joined to one surface of the electrolyte membrane 1 so that the anode gasket 3 is positioned on the electrolyte membrane 1 side, and a back sheet 17 for reinforcing is joined to the other surface of the electrolyte membrane 1. In this state, an anode layer 19 is formed on the electrolyte membrane 1 by applying catalyst paste from the masking film body 9 side. After that, the masking film body 9 is peeled off from the anode gasket 3, and the back sheet 17 is peeled off from the electrolyte membrane. On the cathode side, a projecting back sheet is joined to the anode side in place of the back sheet 17, and in this state, the same process as that on the anode side is conducted. <P>COPYRIGHT: (C)2010,JPO&INPIT |
