Abstract: A fuel cell system comprising an anode compartment which comprises an anode having a copper catalyst layer, a cathode configured as an air cathode and a separator interposed between said anode and said cathode, operable by an amine-derived fuel and oxygen (or air) is disclosed. Further disclosed are fuel cell systems comprising an anode compartment which comprises an anode having a copper catalyst layer, a cathode and a separator interposed between said anode and said cathode, which are operable by a mixture of two types of amine-derived compounds (e.g., ammonia borane, hydrazine and derivatives thereof). Also disclosed are methods of producing electric energy by, and electric-consuming devices containing and operable by, the disclosed fuel cell systems.

Abstract: Fuel cell systems comprising ammonia borane or derivatives thereof as fuel and an anode and/or cathode which comprises a non-noble metal (e.g., copper) or a non-metallic substance (e.g., an iron electron-transfer mediating complex) as a catalyst are disclosed. Fuel cell systems comprising ammonia borane or derivatives thereof as fuel and a peroxide as an oxidant are also disclosed. Uses of the fuel devices are further disclosed.

Abstract: A fueled cell system comprising: an anode compartment comprising a compound having the formula R1R2N—NR3R4, a salt, a hydrate or a solvate thereof, as fuel, and a catalyst layer which comprises copper or a copper alloy; a cathode compartment comprising an oxidant; and a separator interposed between said cathode and said anode compartments, wherein each of R1-R4 is independently selected from the group consisting of hydrogen, alkyl, alkenyl, alkynyl, heteroalicyclic, alkoxy, carboxy, ketone, amide, hydrazide and amine, provided that at least one of R1-R4 is hydrogen.
