Abstract
A deformation absorption member for a fuel-cell-stack disposed between an anode side separator and a cathode side separator. The deformation absorption member includes a thin-board-like base material, and a plurality of raised pieces in which extension portions extended from proximal ends are arranged in a grid pattern. Each raised piece of the plurality of raised pieces is formed in a non-rectangular shape in which the width of the extension portion is shorter than the width of the proximal end, and plurality of raised pieces are configured so that the directions of the extension portions of mutually adjacent raised pieces are alternately arranged, and positions of the proximal ends of the mutually adjacent raised pieces are arranged in at least overlapping positions.
