Single fuel cell and method of manufacturing single fuel cell

A method of manufacturing a single fuel cell, the single fuel cell comprising:

• a membrane electrode assembly including an electrolyte membrane and electrocatalyst layers formed on both side surfaces of the electrolyte membrane, respectively;
• gas diffusion layers placed on both side surfaces of the membrane electrode assembly, respectively;
• and a support frame supporting the membrane electrode assembly on a periphery of the membrane electrode assembly, wherein the support frame comprises:
• a support frame body made of resin;
• and coating layers formed to cover both side surfaces of the support frame body, respectively;
• the method of manufacturing the single fuel cell, comprising:
• providing the membrane electrode assembly in which the gas diffusion layers are placed so that an outer peripheral edge portion remains in one side surface of the membrane electrode assembly;
• forming an adhesive layer on the outer peripheral edge portion;
• placing the support frame, in which an end of an interior portion of the support frame body is exposed, on the adhesive layer so that the support frame is spaced from the gas diffusion layer on the one side surface of the membrane electrode assembly;
• relatively pressing the support frame on the adhesive layer;
• and
• curing the adhesive layer,
• wherein in the step of relatively pressing the support frame on the adhesive layer, the end of the interior portion of the support frame body is covered with a part of the adhesive layer, whereby a protecting layer is formed.
