Abstract
Official abstract text for this publication.
A high-temperature module for electrolysis of water with improved operational safety, in which steam containing at most 1% hydrogen can be made to flow simultaneously in each cathode and in each anode, as a draining gas, of a stack of cells. The stack of cells is housed in a sealed case and a mechanism for clamping by compression of the stack is included. The risks of leaks likely to cause impairments of efficiency and breakages of all or part of a stack EHT electrolyzer are reduced, while a high level of efficiency is provided due to the fact that satisfactory electrical conduction is maintained by compression of the stack.
First claim
Opening claim text (preview).
The invention claimed is: 1. A module for high-temperature electrolysis, comprising: a sealed casing configured to contain steam containing at most 1% hydrogen, or an inert gas; a stack of elementary electrolysis cells, each formed of a cathode, an anode, and an electrolyte sandwiched between the cathode and the anode, wherein at least one interconnecting plate is fitted between two adjacent elementary cells, in electrical contact with an electrode of one of the two elementary c…
