Beschreibung
Zusammenfassung:	The invention concerns an electrode-membrane assembly and a method for making such assemblies for a membrane electrode assembly fuel cell. The electrodes used in the electrode membrane assembly contain proton conductors inserted in and on their active layer. Said assemblies are characterised by the use of two different proton conductors, the proton conductor present on the layer being advantageously of the same type as the one constituting the membrane. Ensemble électrodes-membrane et procédé de réalisation de ces ensembles pour pile à combustible de type PEM. Les électrodes mises en oeuvre dans l'ensemble électrodes-membrane contiennent des conducteurs protoniques introduits dans et sur leur couche active. Les ensembles se caractérisent par l'utilisation de 2 conducteurs protoniques différents, le conducteur protonique présent sur la couche active étant avantageusement de même nature que celui constituant la membrane.
