PROBLEM TO BE SOLVED: To provide a manufacturing method of a membrane electrode laminat ed body for a solid polymer fuel cell capable of stably providing high cell output from a start for a long time. SOLUTION: This manufacturing method of the membrane electrode laminated body for the solid polymer fuel cell is that an electrode having a catalyst layer containing a catalyst and ion exchange resin is jointed onto both surfaces of a solid polymer electrolyte membrane comprising an ion exchange membrane, and after a catalyst layer is laminated onto the both surface of the ion exchange membrane, the obtained laminated body is heat treated at 60-240 deg.C for 5 seconds or more under an environment where oxygen is shut off such as in an inert gas atmosphere. |
