STACK FASTENING STRUCTURE OF FUEL CELL

A stack fastening structure of a fuel cell is provided and includes a fastening mechanism that is mounted at an outside of a plurality of stacked fuel cells to generate a force pressing against the plurality of stacked fuel cells. In addition, an insertion body is mounted within the fastening mechanism to adjust the force pressing against the plurality of fuel cells. Accordingly, the fastening force is more accurately adjusted using the insertion body and the external force applied to the insertion body is measured to calculate the fastening force.
