Abstract:
1. An electrolyzer, comprising: an electrolyzer stack comprising a plurality of electrolyzer cells placed adjacent to one another, wherein each electrolyzer cell comprises an electrode assembly and a diaphragm assembly, and the diaphragm assembly of each electrolyzer cell is placed adjacent to an electrode assembly of another electrolyzer cell; a shell enclosing the stack and coupled to the stack via a resilient mounting member comprising a spring, the shell being spaced from the stack to permit differential thermal expansion of the stack and the shell during operation, wherein the space between the shell and the stack is substantially filled with a non-conductive fluid, wherein the resilient mounting member is configured to allow for the thermal expansion of the stack while maintaining a resilient mounting member pressure on the stack; a gas outlet external to the shell and coupled to the stack; and a volume compensation member enclosed by the shell and configured to apply pressure to the non-conductive fluid, wherein the volume compensation member is fluidically coupled to the gas outlet to receive oxygen, hydrogen, or both from the stack.
