<P>PROBLEM TO BE SOLVED: To provide a fastening structure of a fuel cell stack, capable of correcting changes in surface pressure due to thermal deformation or process deviation. <P>SOLUTION: In the fastening structure of a fuel cell stack 10, end plates 12a and 12b are tightly fitted and fixed on both upper and lower end surfaces of a separator 11. Four peripheral surfaces except for both upper and lower end surfaces of the separator 11 are detachably covered with a pair of U-shaped enclosure panels 14a and 14b. In the detachable fastening structure, a recess formed along the peripheral surface of the end plates 12a and 12b side surfaces engages with a protruding part formed at the edge of upper and lower sides of the enclosure panels 14a and 14b. <P>COPYRIGHT: (C)2008,JPO&INPIT |
