Internally-reinforced water electrolyser module

摘要

A structural plate is provided for an electrolyzer module. The structural plate defines at least one degassing chamber and a half cell chamber opening. The structural plate is reinforced with at least one internal reinforcing means mounted to the structural plate for mitigating outward displacement of the structural plate in response to fluid pressure within the structural plate. The structural plate defines holding features for locating and holding the internal reinforcing means.

主权项

1. An electrolyser module comprising a plurality of structural plates each having a sidewall extending between opposite end faces with a half cell chamber opening and at least two degassing chamber openings extending through said structural plate between said opposite end faces;
said structural plates being arranged in face to face juxtaposition between opposite end pressure plates, each said half cell chamber opening at least partially housing electrolytic half cell components comprising at least an electrode, a bipolar plate in electrical communication with said electrode, and a membrane communicating with said electrode for providing ionic conduction, said structural plates and half cell components defining an array of series connected electrolytic cells surmounted by at least one degassing chamber; said structural plates defining, at least when in face-to-face juxtaposition, passages for fluid flow inside said electrolyser module; said electrolyser module further comprising at least one internal reinforcing member mounted to at least one of said structural plates for mitigating outward displacement of said structural plates; at least said at least one of said structural plates further defining holding features in at least one of a front face and a back face of said structural plates for locating and holding at least part of said at least one internal reinforcing member.
