FUEL-CELL-STACK MANUFACTURING METHOD AND MANUFACTURING DEVICE

[Problem] To provide a fuel cell stack manufacturing method and a manufacturing device that are able to secure the compression amount of the sealing member disposed on the fuel cell module. [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) that are laminated together. In each of these 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 sealed 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.
