Fuel cell stack having intermediate plate for restricting movement of bolt members for fastening stacked body

A fuel cell stack comprising:

• a stacked body having a plurality of stacked unit fuel cells, each unit fuel cell being placed between and supported by a pair of separators, wherein each unit fuel cell has an anode, a cathode, and an electrolyte membrane which is placed between the anode and the cathode;
• fastening plates provided at either end of the stacked body in the stacking direction of the stacked body;
• an intermediate plate provided at an intermediate position of the stacked body in the stacking direction;
• and
• bolt members inserted through the intermediate plate in the stacking direction in a manner such that the movement of the bolt members with respect to the intermediate plate in the direction perpendicular to the stacking direction is restricted so as to fix the relative position between the intermediate plate and the bolt members in the relevant direction,
• wherein the bolt members are also inserted through the fastening plates in the stacking direction, and the stacked body is fastened together by fastening the fastening plates towards the center of the fastening plates by using the bolt members.
