Estimating the term…
The invention relates to inorganic particles which are covalently bonded to first polymer chains made up of at least one polymer carrying proton exchange groups, optionally in the form of salts, and bonded to second polymer chains made up of at least one fluorinated polymer that does not carry any proton exchange groups, the second chains being bonded to the particles via organic spacer groups, or the second chains being bonded to first chains via organic spacer groups, or some of the second chains being bonded to the particles via organic spacer groups while the remaining second chains are bonded to first chains via organic spacer groups.
Proton-conducting membrane for fuel cell formed of inorganic particles bonded, covalently, to first polymer chains constituted of at least one polymer carrying proton-exchanging groups, optionally in the form of salts, said particles also being bonded to second polymer chains constituted of at least one fluorinated polymer not carrying proton-exchanging groups, with the bond between the particles and said second polymer chains corresponding to one of the following alternatives:
