摘要

PPROBLEM TO BE SOLVED: To provide a membrane and catalyst layer junction which is suitable for mass production of a fuel cell and does not deteriorate power generation efficiency per usage amount of a catalyst, a method of manufacturing a polymer electrolyte fuel cell using it, and a device of manufacturing the membrane and catalyst junction. PSOLUTION: This is the method of manufacturing the membrane and catalyst layer junction for the polymer electrolyte fuel cell in which catalyst layers 3 are respectively formed on both sides of an electrolyte membrane 1, and comprises a first process in which a long electrolyte membrane 1 is prepared, a second process in which a transfer film 2 formed with the catalyst layer 3 is prepared on a base material film 5, a third process in which the transfer film 2 is arranged on at least one face of the electrolyte membrane 1 so that the catalyst layer 3 of the transfer film 2 may face the electrolyte membrane 1, and a fourth process in which the catalyst layer 3 of the transfer film 2 is intermittently transferred at desired spacing on at least one face of the electrode membrane 1.
