ABSTRACT:
A spring module is mounted to a fuel cell stack. The spring module includes a first member and a second member capable of inclining relative to each other and moving in a direction toward and away from each other, and a plurality of springs independent of each other and disposed in parallel with each other between the first and second members. The spring module is disposed between an end plate and the pile of fuel cells. The first member includes a first casing, and the second member includes a second casing, whereby the sparing module includes a casing assembly housing the springs. The bottom surface of the casings is deformable to be wavy. The spring module may include a shock absorber. The plurality of springs may include a coil spring and a sponge of a low-resilience type.
