A membrane electrode assembly for a fuel cell is described. The materials for the membrane electrode assembly are formed from sulfonated polymers. A polymer dispersion ink containing the sulfonated polymer and a mixture of solvents is used to form the electrodes on the exchange membrane. The dispersion ink allows for the electrodes to be formed directly on the exchange membrane without significantly dissolving the exchange membrane.
L'invention concerne un assemblage d'électrode à membrane d'une pile à combustible. Les matériaux de l'assemblage de l'électrode à membrane sont formés à partir de polymères sulfonés. Les électrodes sont formées sur la membrane d'échange par application d'une encre contenant le polymère dispersé et un mélange de solvants. L'encre de dispersion permet la formation directe d'électrodes sur la membrane d'échange sans dissolution importante de cette membrane.
