FUEL CELL PRODUCTION METHOD AND FUEL CELL

摘要

[Problem] To provide a fuel-cell-stack manufacturing method capable of increasing the load that a raised piece of a deformation absorption member can receive from the separator unit. [Solution] The deformation absorption member 20 used in the fuel-cell-stack 1 manufacturing method is disposed between an anode side separator 11 and a cathode side separator 12, and comprises a thin-board-like base material 21, and a plurality of raised pieces 22 that are provided raised from one surface 21a of the base material in a grid pattern. In the arrangement step, an extension portion (the free end portion 22b) extended from the proximal end (the fixed end portion 22a) of the raised piece provided on one surface of the base material is disposed so as to be abutted to the cathode side separator or the anode side separator. The setting step sets the interval between the anode side separator and the cathode side separator along the lamination direction X so that the deformation of the raised piece exceeds an elastic deformation region and enters a plastic deformation region, and is also in a region in which the proximal end that is moved due to the deformation will not come in contact with the cathode side separator or the anode side separator.
