Abstract
A fuel cell includes: an electrolyte membrane-electrode structure in which electrodes are provided on both surfaces of an electrolyte membrane and a frame member is joined to the outer peripheral portion of the electrolyte membrane; and a pair of separators for sandwiching the electrolyte membrane-electrode structure, wherein an overlapping portion of the outer peripheral portion of the electrode and the inner peripheral portion of the frame member is disposed in a flow field section in which flow field grooves for allowing a reactant gas to flow along the electrode surface of the electrolyte membrane-electrode structure are formed, and is disposed so as not to extend into buffers between the flow field section and passages.
