Claim:
1. A fuel cell stack manufacturing method having a fuel cell module in which are laminated a plurality of fuel cells, whose membrane electrode assembly, which is made by joining an anode and a cathode on both sides of an electrolyte membrane, is clamped by a pair of separators, the fuel cell stack manufacturing method comprising: a sealing member layout step in which a sealing member is disposed on the outer peripheral part of end surfaces that face each other between at least one of the fuel cell and another adjacent fuel cell, and the fuel cell module is formed by laminating the fuel cells; and a pressure application step in which pressure is applied to the fuel cell module in the lamination direction of the fuel cells thereby forming sealed regions from the sealing members; a lamination-direction thickness of the fuel cell module being controlled by controlling an amount of pressure applied to the fuel cell module in the pressure application step.
