Abstract

A cell stack, in which a plurality of cell units are stacked, is accommodated in a case which has a bottom plate, a first side plate, a second side plate, and a ceiling plate. End plates are arranged at both open ends of the case. The case and the end plates are connected to one another by a hinge mechanism in which pins are engaged into through-holes of tab sections to provide a fuel cell stack.
