FUEL-CELL-STACK MANUFACTURING METHOD AND FUEL-CELL-STACK

摘要

A fuel-cell-stack manufacturing method, includes arranging an extension portion extended from a proximal end of a raised piece on one surface of a base material disposed so as to abut at least one of a cathode side separator and the anode side separator, and setting an interval between the anode side separator and the cathode side separator along a lamination direction so that 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 moved due to the deformation does not come in contact with the cathode side separator or the anode side separator.

1. A fuel-cell-stack manufacturing method, the fuel-cell-stack including
a separator unit comprising an anode side separator and a cathode side separator, a deformation absorption member disposed between the anode side separator and the cathode side separator, and comprising a thin-board-like base material, and a plurality of raised pieces raised from one surface of the base material in a grid pattern, and a membrane electrode assembly adjacent to the separator unit, and formed by joining an anode and a cathode so as to face an electrolyte membrane, the method comprising: arranging an extension portion extended from a proximal end of a raised piece of the raised pieces on the one surface of the base material to be disposed so as to abut at least one of the cathode side separator and the anode side separator, and setting an interval between the anode side separator and the cathode side separator along a lamination direction so that 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 moved due to the deformation does not come in contact with the cathode side separator or the anode side separator.
