Document Type and Number:
WIPO Patent Application WO/2024/004857
Kind Code:
A1
Abstract:
The main objective of the present invention is to provide an electrolyte membrane having good bondability with a catalyst layer, said electrolyte membrane comprising a polymer electrolyte-containing layer (A) and a layer (B) disposed on at least one surface of the layer (A) and being characterized in that a particle concentration (Y1) of the layer (B) in an interface region with the layer (A), as defined below, is higher than a particle concentration (Y2) of the layer (B) in an opposite interface region from the layer (A), as defined below. The particle concentration (Y1) and the particle concentration (Y2) each represent a mass ratio of particles present in the relevant interface region to the total mass of solid content present in the interface region.
