Claim 12:
13. A method of manufacturing a membrane-catalyst assembly including an electrolyte membrane and a catalyst layer bonded to said electrolyte membrane, the method comprising:
a liquid application step of applying, in the atmosphere before bonding, a liquid to only a first surface of said electrolyte membrane wherein a second opposite surface of said electrolyte membrane is attached to a support layer;
a bonding step of thermocompression bonding to a first catalyst layer the first surface of said electrolyte membrane to which said liquid was applied;
separating said support layer from the second surface of said electrolyte membrane;
applying a catalyst solution to the second surface of said electrolyte membrane; and
drying said catalyst solution to form a second catalyst layer.
