The invention relates to an organic ionic conducting membrane for a fuel cell and to its process of manufacture.
This membrane comprises two surface layers (
1, 3
) made of proton conducting polymer, between which is positioned a porous layer (
5
) of proton conducting polymer, the pores of said porous layer containing a proton conducting material (
7
).
The proton conducting polymers of the two surface layers and of the porous layer can be identical or different sulphonated polyimides.
