Abstract
The present invention relates to a cationic support notably forming a hybrid anionic membrane. The present invention notably relates to a cationic support comprising a solid inorganic support comprising pores, said pores comprising at least at the surface, bound through a covalent bond to the inorganic support, a silica gel comprising cationic groups, designated here as “cationic silica gel” or “cationic silica sol”. More particularly, the present invention relates to an anionic membrane for a fuel cell, in particular of the PEM (“polymer exchange membrane”) type.
Claims14
A cationic support wherein said cationic support comprises a solid inorganic support comprising pores, said pores being at least at a surface of said solid inorganic support, wherein a silica gel comprising cationic groups, designated here as “cationic silica gel” or “cationic silica sol” is covalently bound to said inorganic support.
A fuel cell comprising a membrane that comprises a cationic support, wherein said cationic support comprises a solid inorganic support comprising pores, said pores being at least at a surface of the solid inorganic support, wherein a silica gel comprising cationic groups, designated here as “cationic silica gel” or “cationic silica sol”, is covalently bound to said inorganic support.
A biocompatible device comprising a membrane comprising or consisting of a cationic support, wherein said cationic support comprises a solid inorganic support comprising pores, said pores being at least at a surface of the solid inorganic support, wherein a silica gel comprising cationic groups, designated here as “cationic silica gel” or “cationic silica sol”, is covalently bound to said inorganic support.
