Abstract

See full text

Proton-conducting, fluorinated polymer grafted particles for use in the preparation of catalytic layers for fuel cells, such as H2/air cells or H2/O2 cells. The grafted particles include a particle made of a material for catalyzing oxygen reduction or hydrogen oxidation, such as a platinum particle, that has been grafted with a proton-conducting, fluorinated polymer graft. The proton-conducting, fluorinated polymer graft includes an organic spacer group, a single bond or an organic spacer group, a repeating unit resulting from polymerization of a fluorinated styrenic monomer, and a repeating unit resulting, from polymerization of a non-fluorinated styrenic monomer bearing at least one proton-conducting group.
