Abstract
In a method of producing a fuel cell stack, press forming of a first metal separator of a power generation cell is performed to thereby form a first seal line as a seal around at least an oxygen-containing gas flow field. Further, a preliminary load is applied to the first seal line to thereby plastically deform the first seal line. Further, a joint separator and a membrane electrode assembly are stacked together, and a tightening load is applied to the joint separator and the membrane electrode assembly in a stacking direction, to thereby assemble the fuel cell stack.
