Abstract
The present disclosure relates to fuel cells comprising fuel storage materials made from mesoporous N-doped carbon materials. The fuel storage materials comprise a proton conducting polymeric material and a composite material comprising a scaffold of coalesced (N-doped) carbon nanofoam particles, and a coating on the scaffold, said coating comprising N-doped graphitic carbon. The fuel storage materials allow fuel reserves to be stored inside the fuel cell, and are typically incorporated adjacent to an electrode to provide fuel to the electrode when the fuel cell is operating in redox mode.
Claims19
A fuel cell comprising a fuel storage material, wherein the fuel storage material comprises:
- (i) a proton conducting polymeric material;
- and
- (ii) a composite material comprising a superstructure of composite particles, wherein said superstructure comprises:
