Abstract

Official abstract text for this publication.

A casing of a fuel cell stack has stack deformation prevention structure for limiting the change of an interval between end plates on the lower side in a direction of gravity, due to swelling of the lower side of the stack body in the direction of gravity. The stack deformation prevention structure is configured such that elastic modulus of a side plate provided on a lower side of the stack body in the direction of gravity is higher than elastic modulus of a side plate provided on an upper side of the stack body in the direction of gravity.

First claim

Opening claim text (preview).

What is claimed is: 1. A fuel cell stack, comprising: a stack body formed by stacking a plurality of unit cells in a horizontal direction, a pair of end plates sandwiching the plurality of unit cells forming the stack body, the unit cells each including an electrolyte electrode assembly and separators sandwiching the electrolyte electrode assembly, the electrolyte electrode assembly including a pair of electrodes and an electrolyte interposed between the electrodes; and a stack…
