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.
