Summary:In conventional fuel cells that have a structure in which an integrated frame type membrane electrode assembly and a pair of separators have been integrated, the provision of a plurality of protrusions and multi-level sections makes it difficult to achieve miniaturization of the fuel cell. A fuel cell (FC) is provided with a membrane electrode assembly (2) provided with a frame (1), both of which are sandwiched between two separators (3), and is configured such that reactive gas is circulated between the frame (1) and the separators (3). By having a structure in which the frame (1) and both separators (3) each have manifold holes (H1 - H6), and the rims of the manifold holes of frame (1) extend into the manifold holes in the separators (3), and protrusions (11) cover the inner peripheral surfaces of the manifold holes in at least one of the separators (3), it is possible to easily and accurately position and integrate the separators (3) and the frame (1), and fuel cell miniaturization can be achieved because space to position the protrusions (11) is not needed.
