PROBLEM TO BE SOLVED: To provide a gas diffusion electrode joining body and a solid polymer fuel cell, enabling the sue of a perfluorosulfonic ionomer having high proton conductivity and superior performance in a gas diffusion electrode joint producing method for the polymer fuel cell, having high reliability, lower internal resistance, low-humidification or non-humidification operating adaptability and high output. SOLUTION: A multiple functional base compound is added to a catalyst layer or a solid polymer electrolytic membrane of a gas diffusion electrode by giving network crosslinking to the ionomer, thereby preventing the flow of the ionomer out of the layer. |
