Abstract

The invention relates to a fuel cell separator, a fuel cell and a fuel cell battery. It is an object of the present invention to prevent deterioration in sealing performance by suppressing the deformation of manifold portions of a fuel cell separator. A fuel cell separator 10 includes a power generation section 10B provided in a central region on a surface of the separator formed into a plate, a plurality of manifolds 11A, 11B, 12A, and 12B provided in a region closer to the outer periphery than the power generation section 10B, and a reinforcing portion 14A provided so as to extend from a manifold beam portion 15 formed between the plurality of manifolds 11A, 11B, 12A, and 12B to a gap region 13 formed between the power generation section 10B and the manifolds 11A, 11B, 12A, and 12B.

Description

technical field [0001] The present invention relates to a fuel cell separator, a fuel cell and a fuel cell. Background technique [0002] Conventionally, fuel cells including a membrane electrode assembly (MEA: Membrane-Electrode Assembly) formed by providing catalyst layers for electrodes on both surfaces of an electrolyte membrane and separators sandwiching the MEA have been proposed and put into practical use. In the fuel cell system including the fuel cell described above, fuel gas is supplied to one electrode (anode electrode) of the MEA constituting the fuel cell and an oxidizing gas is supplied to the other electrode (cathode electrode) to generate an electrochemical reaction, thereby proceeding. generate electricity. Currently, a technique is employed in which a plurality of single fuel cells having a single MEA are stacked to form a stack (cell stack) to generate large electric power. [0003] The separator constituting the fuel cell is a plate-shaped member havin...
