Abstract: The composite material comprise acid functionalized inorganic supports such as silica dispersed in a functionalized and/or non-functionalized polymer matrix that is based on numerous polymers such as poly(aromatic ether ketones), or poly(benzoyl phenylene), or derivatives thereof. The composite material is characterized by good water retention capabilities due to the acidic functions and the hydrophilicity of the silica particles. Moreover, a good impermeability to gas and liquid fuels commonly used in fuel cell technology, like hydrogen gas or methanol solution, is also obtained due to the presence of silica particles. Good mechanical properties of the composite material let the material to be formed easily in thin film or membrane form. In that form, the composite material is usable for proton exchange membrane for fuel cells, for drying or humidifying membrane for gas or solvent conditioning, or as acid catalytic membrane.

Abstract: The catalyst-coated membrane has a proton exchange membrane with two opposite sides, and a catalyst coating applied directly to one of the two sides, the catalyst coating having a plurality of openings defined therethrough and scattered thereacross, the openings defining passages to the proton exchange membrane in which corresponding electro-chemical active surfaces of the catalyst coating are exposed. The openings can be defined in the catalyst coating after application thereof or during application thereof.
