Proton conductive membrane, useful for proton exchange membrane fuel cell, comprises a multilayer stack

摘要

Proton conductive membrane (8) comprises a multilayer stack of (A-B1) ntype or (A-B1-A) ntype, where: A is a first thin layer (10), formed from a proton conductive material; B1 is a second thin layer (11), consisting of a material different from the material forming the first thin layer and comprising pores filled by the proton conductive material; and n is an integer strictly greater than 1.
