Abstract
A manufacturing method of a fuel cell stack includes: stacking fuel cells on a first end plate; superposing a pressure plate, on which protruding portions are provided along an outer periphery thereof, on a stacked body of the fuel cells so that the protruding portions protrude outward from side faces of the stacked body; pressing the protruding portions so that the stacked body is pressed between the first end and the pressure plates; measuring a length of the stacked body in a stacking direction while pressing the protruding portions; superposing on the pressure plate an adjustment plate having a thickness in accordance with the measured length while pressing the protruding portions; and fixing a second end plate to the first end plate so as to sandwich the stacked body, the pressure plate and the adjustment plate between the first and the second end plates while pressing the protruding portions.
