Abstract

The invention provides an attachment structure for a deformation absorption member that makes it possible to prevent a base end from rising upward while preventing excessive plastic deformation of the base end even when a load is applied to a raised piece of the deformation absorption member. The attachment structure for a deformation absorption member (20) is arranged for use between an anode-side separator (11) and a cathode-side separator (12). The deformation absorption member is provided with raised pieces (22) and a joining section (23). The raised pieces are provided in a grid pattern and rise from one surface (21a) of a substrate (21), and extended sections that extend from the base ends of the raised pieces are brought into contact with the cathode-side separator. The joining section is formed so as to be partially joined to the anode-side separator between the base end of one raised piece (22M) and the base end of another raised piece (22N) that is adjacent to the one raised piece (22M) in a direction (Z) that intersects a direction (Y) that follows the one raised piece from the base end to the extended section side thereof.

Description

technical field

[0001] The present invention relates to an installation structure and an installation method of a deformation absorbing member. Background technique

[0002] Conventionally, a fuel cell is constructed by alternately stacking a plurality of separators and a plurality of membrane electrode assemblies. Since a fuel cell obtains a high output corresponding to the number of stacks of separators and membrane electrode assemblies, it is desirable to increase the number of stacks. By bringing the multi-layered separator and the membrane electrode assembly into sufficiently close contact with each other, the electrical resistance can be reduced and desired battery performance can be achieved.

[0003] However, in the separator unit composed of the anode-side separator and the cathode-side separator, the fuel gas (hydrogen gas) of the anode-side separator and the part of the cooling water flow path and the oxidant gas (oxygen-containing oxygen) of the cathode-side sep...
