Researchers at UCLA, with colleagues at UC Irvine, have designed a graphene-nanopocket-encaged platinum cobalt (PtCo@Gnp) nanocatalyst for fuel cells with good electrochemical accessibility and exceptional durability under a demanding ultralow PGM loading (0.070 mg PGM cm –2 ) due to the non-contacting enclosure of graphene nanopockets. The PtCo@Gnp delivers a state-of-the-art mass activity of 1.21 A mg PGM –1 , a rated power of 13.2 W mg PGM –1 and a mass activity retention of 73% after an acce
