Engineered architecture of nitrogenous graphene encapsulating porous carbon with nano-channel reactors enhancing the PEM fuel cell performance

Engineered architecture with nano-channel reactors are constructed by wrapping graphenized sheets on graphitic meso-porous carbon spheres. This heterostructures with large electroactive surface area, abundant pore channels, and tuned chemical structures impart improved fuel cell performance by providing easily accessible active sites, effective mass transfer, and smooth charge transfer.300
