example 1

[0042] Example 1 The stresses in the structural plates for the electrolyser modules according to the existing design were modeled by finite element analysis (FEA). The general structural plate configuration is as follows: Image 6 shown in . The outermost dimensions of the structural plate are 1505mm wide, 1,828mm high and 12mm thick. Half-cell chamber opening is 6,000cm 2 . The structural panels are made of polysulfone. Modeling at 25 bar internal pressure showed an unacceptable stress distribution with high stresses and displacements.

[0043] Example 2 The stresses in the structural plates for electrolyser modules according to the invention were modeled by finite element analysis (FEA). The general configuration of structural panels and external reinforcement devices is as follows: Figure 4 shown in . The external reinforcement 60 is a steel cross bar. The outermost dimensions of the structural plate are 1,476mm wide, 1,773mm high and 12mm thick. Half-cell chamber opening is 6,000cm 2 . The structural panels are made of polysulfone. The amount of polysulfone used is Image 6 A 41% reduction in parts is shown in the existing design. Modeling at 25 bar internal pressure showed acceptable stress distribution with low stress and displacement.

[0044] Although the above embodiments have focused on electrolyser modules, the same principles can be applied to electrolyser stacks. For example, the electrolyser stack includes a plurality of structural plates each having side walls extending between opposin...

Abstract

A structural plate with external reinforcing means is provided for an electrolyser module. The structural plate defines at least one degassing chamber and a half cell chamber opening. The external reinforcing means contact the structural plate for mitigating outward displacement of the structural plate in response to fluid pressure within the structural plate. The structural plate and the external reinforcing means define interlocking features for achieving contact and corresponding mechanical reinforcement.

Description

technical field [0001] This invention relates to the design of water electrolyzers for the production of hydrogen and oxygen at high pressures, and more particularly to alkaline and polymer electrolytic membrane (PEM) type electrolyzer stacks and Electrolyzer modules and their corresponding components. Background technique [0002] Electrolyzers use electricity to convert reactant chemicals into desired product chemicals through electrochemical reactions (ie, reactions that occur at electrodes in contact with an electrolyte). Hydrogen is a product of increasing demand for its use in chemical processes and potentially also in hydrogen vehicles and devices powered by hydrogen fuel cell engines or hydrogen internal combustion engines (or also in part by battery-powered hybrid hydrogen vehicles) Taste. Water electrolysers, which use water and electricity to produce hydrogen and oxygen, are the most common type of electrolyser used to produce gaseous hydrogen as the main produc...
