Patent ID: 8722569

Claim:
A fuel cell comprising particles for increasing the hydrogen peroxide radical resistance, said particles comprising: a metal oxide comprising colloid particles selected from the group consisting of alumina, silica, TiO 2 , Ti 2 O 3 , zirconium oxide, manganese dioxide, manganese oxide, Y 2 O 3 , Fe 2 O 3 , FeO, tin oxide, copper oxide, nickel oxide, tungsten oxide, germania, CeO 2 , Ce 2 O 3 , and combinations thereof, a stabilizer selected from the group consisting of metal ions and metalloid ions, and combinations thereof, and at least one catalyst different from the stabilizer and selected from the group consisting of cerium metal, cerium ions, ruthenium metal, and ruthenium ions; wherein the stabilizer metal ions or metalloid ions and catalyst metal or metal ions have been reacted onto the metal oxide particles to obtain multi-metal surface-modified particles.
