FUEL CELL

Provided is a fuel cell capable of maintaining an interface pressure in good condition between a membrane electrode assembly and separators, and preventing an increase in contact resistance. A fuel cell is disclosed including: a membrane electrode assembly provided with a frame at a periphery thereof; two separators holding both the frame and the membrane electrode assembly therebetween; and a gas seal provided between an edge portion of the frame and an edge portion of each separator to have a configuration in which a reactant gas passes through the frame and the membrane electrode assembly and the separators, wherein the frame and the separators are not in contact with and separated from each other in a region between the membrane electrode assembly and the gas seal.
