ABSTRACT:
A production method for a fuel cell including an electrolyte, an anode which is provided on one of both sides of the electrolyte, a cathode which is provided on the other side of the electrolyte, and separators one of which is provided on an outer side of the anode and the other of which is provided on an outer side of the cathode. This production method includes a first process in which the anode and the cathode each of which includes at least a catalyst and an ion-exchange resin are produced; and a second process in which the electrolyte is provided between the anode and the cathode before being formed into a thin-film electrolyte. With this production method, contact resistance can be reduced without increasing the number of production processes.
