Abstract
A compact fuel cell stack in which a plurality of fuel cells are arranged in a stack between end plates. Resilient means such as springs are connected between the end plates, imposing on the end plates a force which urges the end plates together to apply a predetermined compressive loading to the cells. The springs are entirely disposed in the space between the end plates and do not extend exteriorly above or below the end plates, thereby reducing the overall stack height and weight as compared with conventional structures. Force adjusting means to adjust the force imposed by the resilient means are preferably included.
