摘要： A recyclable fuel distribution system comprising a hierarchy of operatively linked (with fuel supply and reaction product collection elements) fluid fuel transport vehicles, fluid fuel storage tanks, fuel supply reservoirs (optional depending on specific use), and fluid fuel usage devices operatively linked to the storage tanks or supply reservoirs, as applicable. The fuel, during use, undergoes a reversible chemical reaction, whereby collected reaction product is reversible to the original fuel. At least one and preferably all of the vehicles, storage tanks and reservoirs contain a storage volume with separated chambers, adapted to inversely change relative to fuel being supplied and reaction product being collected and stored. As a result, a single volume during transport, storage, and use, provides the dual function of fuel supply and collection of reversible reaction product, with concomitant nearly halving of transport, storage and use volumes and costs. Electrical production with a zinc fuel which reversibly forms a zinc oxide reaction product is a particularly suitable fuel for the present system for use in large scale fuel cell applications. Applications range from large scale megawatt power levels for industrial levels to tens of kilowatts for homes and transportation systems down to several watts for portable electrical and electronic appliances and devices.

摘要： An air depolarized cell with at least one movable cathode element disposed in an active anode metal material which is in a fluid or paste state. The cathode element(s) continuously moves to maintain electrochemical proximity with active anode material as the active anode material is converted into electrochemical cell reaction product. In one embodiment, formation of cell reaction products of increased volume relative to initial anode volume serves to propel the movable cathode through the anode material. Viscosity of the fluid or anode paste is adjusted to ensure cathode movement relative to active anode for maximized utilization.

摘要： In an air-metal fuel cell battery (FCB) system, wherein metal-fuel tape, the ionically-conductive medium and the cathode structures are transported at substantially the same velocity at the locus of points at which the ionically-conductive medium contacts the moving cathode structure and the moving metal-fuel tape during discharging and recharging modes of operation. In a first generalized embodiment of the present invention, the ionically-conductive medium is realized as an ionically-conductive belt, and the metal-fuel tape, ionically-conductive belt, and movable cathode structure are transported at substantially the same velocity at the locus of points which the ionically-conducing belt contacts the metal-fuel tape and the cathode structure during system operation. In a second generalized embodiment of the present invention, the ionically-conductive medium is realized as a solid-state (e.g. gelatinous) film layer integrated with the metal-fuel tape. In a third generalized embodiment of the present invention, the ionically-conductive medium is realized as a solid-state film layer integrated with the movable cathode structure. By transporting the movable cathode structure, ionically contacting medium and metal-fuel tape within the system as described above, generation of frictional forces among such structures are minimized during system operation, and thus the damage to the cathode structure and metal-fuel tape is substantially reduced.
