ATTACHMENT STRUCTURE FOR DEFORMATION ABSORPTION MEMBER AND ATTACHMENT METHOD

摘要

An attachment structure for a deformation absorption member of a fuel-cell-stack includes a first raised piece raised from one surface of a base material in a grid pattern, and having an extension portion extending from a proximal end, the extension portion abutting at least one of the cathode side separator or the anode side separator, a second raised piece having a proximal end, and a joint portion formed by partially joining a location between the proximal end of the first raised piece and the proximal end of the second raised piece, proximal end of the first raised piece being adjacent the proximal end of the second raised piece in a second direction that intersects a first direction taken from the proximal end of the first raised piece to an extension portion side, to the at least one of the anode side separator and the cathode side separator.

1. An attachment structure for a deformation absorption member of a fuel-cell-stack used disposed between an anode side separator and a cathode side separator, comprising:
a first raised piece raised from one surface of a base material in a grid pattern, and having an extension portion extending from a proximal end, the extension portion abutting at least one of the cathode side separator or the anode side separator; a second raised piece having a proximal end; and a joint portion formed by partially joining a location between the proximal end of the first raised piece, and the proximal end of the second raised piece, proximal end of the first raised piece being adjacent the proximal end of the second raised piece in a second direction that intersects a first direction taken from the proximal end of the first raised piece to an extension portion side, to the at least one of the anode side separator and the cathode side separator.
