FUEL CELL STACK MANUFACTURING METHOD AND MANUFACTURING DEVICE

摘要

[Problem] To provide a fuel-cell-stack manufacturing method and manufacturing device that ensure that sealing members in a fuel-cell module are sufficiently compressed. [Solution] The present invention is a method for manufacturing a fuel-cell stack (100) that contains a laminate (30) comprising of a plurality of fuel cells (30a) laminated together. In each of said fuel cells (30a), an MEA (31) comprising an anode (31b) and a cathode (31c) joined respectively to the two sides of an electrolyte membrane (31a) is sandwiched between a pair of separators (32a, 32b). The aforementioned method has the following steps: a sealing-member layout step in which fuel cells (30) with sealing members (70) applied at least between adjacent fuel cells are laminated together, forming a fuel-cell module; and a pressure-application step in which pressure is applied to the fuel-cell module in the lamination direction of the fuel cells, forming seal regions from the sealing members. The lamination-direction thickness of the fuel-cell module is controlled by controlling the amount of pressure applied to the fuel-cell module in the pressure-application step.
