A composite membrane includes a compatibilized porous base membrane and an ion exchange material, which is impregnated into the compatibilized porous base membrane. The base membrane is compatibilized by coating a primer to external and internal surfaces of the porous base membrane and crosslinking the primer. A method for making the membrane, a proton exchange membrane for a fuel cell and a method form making the proton exchange membrane are also provided. The composite membrane is durable, compatible, highly conductive and mechanically stable.
