Electrosprayed catalyst layers based on graphene–carbon black hybrids for the next-generation fuel cell electrodes
Here, we report a novel electrode structure with graphene and graphene–carbon black hybrids by electrospraying for polymer electrolyte membrane fuel cells. After syntheses of platinum (Pt)/partially reduced graphene oxide (rGO) and Pt/r-GO/carbon black (CB) hybrid electrocatalysts, suspensions of sy...
