Abstract

Disclosed herein are membraneless direct liquid fuel cells comprising an anode comprising an anode catalyst; a cathode comprising a cathode catalyst; an aqueous solution comprising a fuel, an electrolyte, and water; an oxygen source in electrochemical contact with the cathode catalyst; wherein the anode catalyst and the cathode catalyst are in electrochemical contact with the aqueous solution; wherein the anode catalyst is catalytically active for the oxidation of the fuel; wherein the cathode catalyst is catalytically active for the reduction of oxygen and is substantially catalytically inactive for the oxidation of the fuel. Also disclosed herein are catalysts that are catalytically active for the oxygen reduction reaction and/or the oxygen evolution reaction and substantially catalytically inactive for the oxidation reaction of a fuel.
