A method of manufacturing a fuel cell is characterized by comprising: a hydrogen permeable membrane forming step of forming a second hydrogen permeable membrane 30 on a first hydrogen permeable membrane 10; and an electrolyte layer forming step of forming an electrolyte layer 40 on the second hydrogen permeable membrane 30. In this case, it is possible to form the electrolyte layer 40 having few defects. Adhesiveness is therefore improved between the electrolyte layer 40 and the second hydrogen permeable membrane 30. Accordingly, a separation is restrained between the electrolyte layer 40 and the second hydrogen permeable membrane 30.

La présente invention concerne un processus de production de pile à combustible présentant les caractéristiques suivantes : une étape de préparation dans laquelle une première membrane de séparation d'hydrogène (10) est préparée, une étape de formation de membrane de séparation d'hydrogène dans laquelle une seconde membrane de séparation hydrogène () est formée sur un côté de la première membrane de séparation d'hydrogène (10). Par ce processus, un film d'électrolyte (40) exempt de défaut peut être formé. Par conséquent, l'adhésion entre ce film d'électrolyte (40) et la seconde membrane de séparation d'hydrogène (30) est améliorée. On peut ainsi empêcher ce film d'électrolyte (40) d'être arraché de la seconde membrane de séparation d'hydrogène (30).
