Abstract

The present invention provides a fuel cell capable of smoothly flowing a reaction gas or a cooling medium with a small and compact structure. The fuel cell (10) includes a first electrolyte membrane-electrode structure (16a) in which a first resin frame member (58) is integrally molded. The first resin frame member (58) is provided with resin wall portions (67a, 67b) that form the outer peripheral portion of the first oxidant gas flow path (26). The resin wall portions (67a, 67b) are provided with thin-walled portions (67at, 67bt) at positions overlapping the inlet cooling medium connection portion (33a) and the outlet cooling medium connection portion (33b) in the stacking direction, and the inlet cooling medium connection portion ( 33a) and the outlet cooling medium connecting portion (33b) connect the cooling medium flow path (32) to the cooling medium inlet communication hole (25a) and the cooling medium outlet communication hole (25b).

Description

technical field [0001] The present invention relates to a fuel cell in which an electrolyte membrane-electrode structure is provided with a pair of electrodes on both sides of an electrolyte membrane and a separator is laminated, and a resin frame member is provided on the outer periphery thereof. Background technique [0002] For example, a solid polymer fuel cell constitutes a power generation cell in which an electrolyte membrane-electrode structure (MEA) is sandwiched between a solid polymer electrolyte composed of a polymer ion exchange membrane through separators. An anode electrode and a cathode electrode are respectively provided on both sides of the membrane. A fuel cell generally constitutes a fuel cell stack by stacking a plurality of power generation cells, and is used, for example, as a vehicle-mounted fuel cell system by being incorporated into a fuel cell vehicle. [0003] In a fuel cell, a so-called internal manifold is often configured to supply a fuel gas ...
