Abstract

Abstract A support assembly, including an end plate, for use in metal gas cells. The support assembly inhibits a plate stack (20) which is positioned within a pressure vessel (12) from impinging the walls of the pressure vessel. The support assembly comprises a first and a second weld ring (60, 62) and a first and a second end plate (50, 52), each of the end plates being attached to a different end of the plate stack (20). The first and second weld rings (60, 62) mate with the first and second end plates (50, 52), respectively, and cooperate to support the plate stack. The end plate comprises two plates secured together. A raised portion on one of the plates forming the end plate has a radially extending embossment formed therein to increase the rigidity thereof. The pressure vessel (12) is constructed of generally cylindrical container (14) defining two circumferentially extending lips, each of which is secured to an end portion (16, 18).
