Embodiment Construction

[0030] Such as figure 1 and 2 As shown, the power generation cell (fuel cell) 12 according to the present invention includes a frame-equipped membrane electrode assembly 10 (hereinafter referred to as "frame-equipped MEA 10"), and The first partition 14 and the second partition 16 . For example, the power generation cell 12 is a laterally elongated (or longitudinally elongated) rectangular solid polymer electrolyte fuel cell. A plurality of power generation cells 12 are stacked together in the horizontal direction shown by arrow A, or in the direction of gravity shown by arrow C, to form the fuel cell stack 11a. For example, the fuel cell stack 11a is installed as an in-vehicle fuel cell stack in a fuel cell electric vehicle (not shown).

[0031] In the power generation cell 12 , the frame-equipped MEA 10 is sandwiched between a first separator 14 and a second separator 16 . Both the first separator 14 and the second separator 16 have a laterally elongated (or longitudinal...

Abstract

A frame equipped membrane electrode assembly (10) includes a membrane electrode assembly (10a) and a frame member (24). The frame member (24) includes a first frame shaped sheet (24a) and a second frame shaped sheet (24b). An inner peripheral portion of the first frame shaped sheet (24a) is joined to an outer peripheral portion of the membrane electrode assembly (10a). The inner peripheral portion(24an) of the first frame shaped sheet (24a) is disposed between an outer peripheral portion (20c) of an anode (20) and an outer peripheral portion (22c) of a cathode (22). A gap (G) is formed between an inner end (24be) of the second frame shaped sheet (24b) and an outer end (22e) of the cathode (22). The first frame shaped sheet (24a) and the second frame shaped sheet (24b) are joined togetherover the entire periphery by an adhesive layer.

Description

technical field [0001] The present invention relates to a frame-equipped membrane electrode assembly, a production method of the frame-equipped membrane electrode assembly, and a fuel cell. Background technique [0002] In general, solid polymer electrolyte fuel cells employ solid polymer electrolyte membranes. Solid polymer electrolyte membranes are polymer ion exchange membranes. In the fuel cell, the anode is arranged on one surface of the solid polymer electrolyte membrane, and the cathode is arranged on the other surface of the solid polymer electrolyte membrane to respectively form a membrane electrode assembly (membrane electrode assembly, MEA). [0003] The membrane electrode assembly is sandwiched between separators (bipolar plates) to form a power generating cell (unit fuel cell). In use, a predetermined number of power generating cells are stacked together to form a fuel cell stack. For example, a fuel cell stack is mounted on a vehicle as an in-vehicle fuel ce...
