A robust single compartment peroxide fuel cell using mesoporous antimony doped tin oxide as the cathode material.

To date, metal oxide catalysts have not been explored as cathode materials for robust and high-performance single-compartment HO fuel cells due to significant non-electrochemical disproportionation losses of HO on many metal oxide surfaces. Here, for the first time, we demonstrate an acidic peroxide fuel cell with antimony doped tin oxide as the cathode and widely used Ni foam as the anode material. Our constructed peroxide fuel cell records a superior open circuit potential of nearly 0.
