ELECTRODE ASSEMBLY FOR A FUEL ELEMENT WITHOUT A PROTON EXCHANGE MEMBRANE, A METHOD FOR ITS PRODUCING AND A FUEL ELEMENT Russian patent published in 2023 - IPC H01M8/1004 

FIELD: fuel elements.

SUBSTANCE: electrode assembly for a fuel element without a proton exchange membrane, a method for its production and a fuel element. The electrode assembly contains a polymer electrolyte layer, a negative pole catalyst layer and a positive pole catalyst layer located on two surfaces of the polymer electrolyte layer, and a negative pole diffusion layer located on the negative pole catalyst layer at a distance from the polymer electrolyte layer, as well as a positive pole diffusion layer located on the positive pole catalyst layer away from the polymer electrolyte layer, wherein the polymer electrolyte layer is grown on the negative pole catalyst layer and/or the positive pole catalyst layer. The polymer electrolyte layer material of this electrode assembly contains only a polymer electrolyte, and there is no need for a separate conventional proton exchange membrane.

EFFECT: solution to the problem of swelling of the proton exchange membrane at high temperatures, reducing the cost of production.
