COMPRESSION CASING FOR A FUEL CELL STACK AND A METHOD FOR MANUFACTURING A COMPRESSION CASING FOR A FUEL CELL STACK

摘要

A fuel cell or electrolysis cell stack has force distribution members with one planar and one convex shape applied to at least its top and bottom face and in one embodiment further to two of its side faces. A compressed mat and further a rigid fixing collar surrounds the stack and force distribution members, whereby the stack is submitted to a compression force on at least the top and bottom face and potentially also to two side faces. The assembly is substantially gas tight in an axial direction of the primarily oval or circular shape and can be fitted with gas tight end plates to form robust gas inlet and outlet manifolds.
