A recharger includes a manifold having an input to couple to a hydrogen generating module and an output port to couple to at least one rechargeable fuel cell. A vacuum pump is coupled to the manifold to evacuate the manifold. A valve is coupled to the manifold between the vacuum pump and the input of the manifold. A controller is coupled to control the vacuum pump and the valve, as well as an optional fan.

A method for preparing a flexible membrane-free and wire-shaped fuel cell is provided. A carbon nanotube sheet is twisted and loaded with a catalyst to obtain a (CNT)@Fe.sub.3[Co(CN).sub.6].sub.2 cathode electrode; the carbon nanotube sheet is twisted and coated with a nickel powder to obtain a CNT@nickel particle anode electrode; and the (CNT)@Fe.sub.3[Co(CN).sub.6].sub.2 cathode electrode, the CNT@nickel particle anode electrode, and a fuel electrolyte of H.sub.2O.sub.2 are integrated in a silicone tube to obtain a flexible membrane-free and wire-shaped fuel cell. The flexible membrane-free and wire-shaped fuel cell of the present invention can generate an open-circuit voltage of 0.88 V, while having very good flexibility, and can be woven into textiles such as clothes, thereby having great application prospects in the field of portable energy supply.

The present application provides a new type of glucose fuel cell in which a layer of proton-conducting metal oxide is interposed between the anode and cathode electrodes. Such metal oxides can serve in the form of thin-layer fuel cell membrane materials for novel, all-solid state fuel cell designs.

In various embodiments, a solid oxide fuel cell is fabricated in part by disposing a functional layer between the cathode and the solid electrolyte.

According to an exemplary embodiment, an electronic luggage device may be disclosed. The electronic luggage device may be fully TSA compliant. The device may be capable of communicating both wirelessly and by wired connection(s) to other devices. The electronic luggage device may also charge other devices by battery and in turn be charged by other electric power facilities. The electronic luggage device may have GPS capabilities, an intelligent “sleep-mode,” multiple various charging and communicatory ports, a recessed telescoping handle fixture, a hidden battery compartment, and a high capacity removable battery. The removable battery may be retained by any locking means understood by a person having ordinary skill in the art. The removable battery may be automatically or manually ejected. This may be accomplished by a spring-loaded force, a slot and rail system, or equivalents as would be understood by a person having ordinary skill in the art.

A method of fabrication produces one or more functional microparticles using a parallel pore working piece. In one embodiment, the method forms a particle that includes a segment for the oxidation of a biofuel (such as glucose) and the reduction of oxygen. The particle may be synthesized in a structure with defined and parallel, uniform, thin pores that completely penetrate the structure. Further, the functional microparticle may be configured to reside in a human or animal body or cell such that it may be self-contained fuel cell having an anode, a cathode, a separator membrane, and a magnetic component. In other embodiments, the functional microparticles may deliver energy or therapeutic materials in the body.

A metal-air battery comprises a casing including a first surface having breathability and second surface different from the first surface; and a positive electrode housed in the casing, a negative electrode housed in the casing, a positive-electrode terminal electrically connected to the positive electrode and exposed from the casing, a negative-electrode terminal electrically connected to the negative electrode and exposed from the casing, and an adhesive layer containing an adhesive and provided on a portion of the second surface.

A laminated secondary battery that houses an electrode assembly and an electrolyte in an exterior body. In the electrode assembly, a positive and negative electrode laminate body including an electrode current collector and electrode multi-units having two or more electrode material layers formed on the electrode current collector with non-forming regions interposed between them is bent on the non-forming regions.

A fuel cell includes a pair of separators for clamping a laminate including a membrane electrode assembly, an anode gas diffusion layer, and a cathode gas diffusion layer, and a frame formed from thermosetting resin and disposed between the separators to surround a periphery of the laminate. At least one of the anode and the cathode gas diffusion layers is formed from a composite of thermoplastic resin and conductive particles, and includes a protrusion protruding beyond a level of a surface of the frame which faces one of the separators in a state that the laminate is not clamped between the separators under a predetermined pressure. The one of the separators presses the protrusion and gets the one of the gas diffusion layers to be deformed and put into contact with the frame in a state that the laminate is clamped between the separators under the predetermined pressure.
