A cathode layer structure for a solid polymer fuel cell is disclosed. It comprises a composite cathode layer (48) of catalyst (11), anion ion conducting polymer (12) and cation conducting polymer (14). The interface between the anion ion conducting polymer (12) and the cation conducting polymer (14) is located entirely within the cathode layer (48). In particular the catalyst (11) is embedded in said anion conducting polymer (12), and the cation conducting polymer (14) encloses regions of said anion conducting polymer (12).
L'invention concerne une structure de couche cathodique pour une pile à combustible polymère solide. La structure comprend une couche cathodique composite (48) de catalyseur (11), un polymère conducteur anionique (12) et un polymère conducteur cationique (14). L'interface entre le polymère conducteur anionique (12) et le polymère conducteur cationique (14) est entièrement située dans la couche cathodique (48). Plus spécialement, le catalyseur (11) est incrusté dans ledit polymère conducteur anionique (12), et le polymère conducteur cationique (14) renferme des régions de ce polymère conducteur anionique (12).
