A method of clamping a fuel cell stack includes a stack preliminary clamping step, a stack pre-treatment step of performing a gas flow rate variation cycle or a clamping pressure variation cycle, wherein the gas flow rate variation cycle repeatedly changes a flow rate of a gas supplied to an anode and a cathode included in the preliminarily clamped stack, and wherein the clamping pressure variation cycle repeatedly increases and decreases the clamping pressure by pressurization and pressure release of the preliminarily clamped stack using the pressure tool, and a stack main clamping step of correcting a variation in clamping pressure occurring due to a variation in thickness of a gas diffusion layer to mainly clamp the stack after the stack pre-treatment step. |
