▎ 摘 要
NOVELTY - A catalyst comprises graphene-polypyrrole composite material as carrier and 10-60 wt.% noble metal active component loaded on the carrier. USE - Catalyst for use as an anode or a cathode for a fuel cell . ADVANTAGE - The catalyst has high specific surface area, high conductivity and high stability, and reduces loss of noble metal, hence noble metal agglomeration is suppressed.
