Method of manufacturing unit fuel cell

A method of manufacturing a unit fuel cell, comprising:

• integrating a first gas diffusion layer on a first side surface of a membrane electrode assembly consisting of an electrolyte membrane and electrode catalyst layers, one of which is disposed at one side of the electrolyte membrane and the other of which is disposed at the other side of the electrolyte membrane;
• forming an adhesive layer having ultraviolet curability and heat curability on an outer peripheral edge portion of a second side surface of the membrane electrode assembly;
• disposing a support frame which supports the membrane electrode assembly at an outer periphery of the membrane electrode assembly so that an inner peripheral edge portion of the support frame is disposed on an outer portion of the adhesive layer;
• disposing a second gas diffusion layer so that an outer peripheral edge portion of the second gas diffusion layer is disposed on an inner portion of the adhesive layer;
• and
• integrating the membrane electrode assembly integrated with the first gas diffusion layer, the second gas diffusion layer and the support frame by curing the adhesive layer.
