  • Publication number: 20240059922
    Abstract: A method may form an electroconductive and hydrophobic microporous layer (MPL) at an active layer surface configured for an electrochemical converter, including: (a) providing a non-aqueous dispersion, called “ink”, including a carbon-based particulate material and an organic solvent; (b) forming an ink deposit at the active layer surface; and (c) evaporating the solvent(s) to form a microporous layer, simultaneously and/or subsequently to the forming (b). The ink may include poly(vinylidene fluoride-co-hexafluoropropene), dissolved in the organic solvent. Ink may prepare such a microporous layer, and a multilayer structure including an active layer supported by a solid electrolyte membrane and contacting, at its face on the opposite side the solid membrane, with a microporous layer obtained by the such a method. A membrane-electrode assembly may include such a multilayer structure. Such an MEA may be used in an individual cell of an electrochemical converter, in particular in a PEMFC.
