Abstract

Disclosed is a fuel cell provided with a membrane electrode structure having a frame, two separators that sandwich the membrane electrode structure therebetween, and gas seals between the end portion of the frame and the end portions of respective separators, and diffuser sections for distributing a reacting gas to between the frame and respective separators. In the diffuser section on the cathode side, the frame is provided with a protruding section in contact with the separator, and in the diffuser section on the anode side, the frame and the separator are disposed by being spaced apart from each other, thereby excellently maintaining contact surface pressure between the membrane electrode structure and the separators, and preventing contact resistance from being increased.
