Abstract
A membrane-electrode assembly (MEA) including a membrane and two electrodes, and further at least one layer located at the interface of the membrane and of an electrode. The layer contains a proton conductive polymer which has a glass transition temperature lower than or equal to, advantageously lower than, that of the proton conductive polymer contained in the membrane.
