PURPOSE:To provide a cell stack for a fuel cell which is compact and has high maintenance capability. CONSTITUTION:A cell stack S1 for a fuel cell has a stacked body 3 formed by stacking plural unit cells C1 having plural projecting lines 40 which are uniformly arranged in a circumferential direction on the outer side of an outer frame 12 and are formed in two steps in a unit cell stacking direction. Plural both projecting lines 40 in which adjacent both unit cells C are facing each other are compressed by plural channel-shaped springs 41. Formation of dead spaces in the circumference of the stacked body 3 is avoided, and when only a specific unit cell C1 is replaced, only the spring 41 used for reinforcing the unit cell C1 is removed, then mounted again after the unit cell C1 was replaced. |
