Summary:PURPOSE: A fuel cell stack connecting method is provided to maintain stable and optimized connecting state without any problems like connecting pressure reduction, generation of micro gap, etc. CONSTITUTION: A fuel cell stack connecting method comprises: a step of connecting end plate to the laminate of unit cells; a stack pre-coupling step setting and fixing connecting units for maintaining connection pressure; a step conducting coupling pressure variation cycles or gas flux change cycles; and a stack coupling step connecting stacks by compensating connection pressure change value after the stack pre-treatment step.
