Use of Pd-Pt loaded graphene aerogel on nickel foam in direct ethanol fuel cell

Pd-Pt/GA/NFP electrode was prepared by one-step, binder-free, and green method via mild conditioned hydrothermal reduction, which was used as anode of batch-type DEFC unit. The Pd-Pt/GA/NFP achieved the best performance with a Pd/Pt atomic ratio of 1:0.98 under a 4 M ethanol/5 M KOH solution in a DEFC unit with corresponding power output of 3.6 mW cm−2.292
