Abstract: Consumer battery which comprises an electricity generating unit (EGU) 100 and a fuel carrying unit (FCU) 200 that form a passive tubular fuel cell. The EGU comprises an outer tubular collector 130 and an inner tubular collector 140, so that the parts of the EGU are arranged between both collectors and the inner collector applies an outward pressure on said parts. The EGU also comprises two adjacent electricity generating tubular cells 110 and 120 that are connected in series and that can be arranged either consecutively or concentrically. Each tubular cell comprises a proton exchange membrane that, on each side, has a catalyst and a gas diffuser, and also comprises two or more cylindrical seals for sealing the cell and preventing gas leakage.

Abstract: An electrochemical element or cell and a cathode for same which contains an anode, a separator, and a cathode composed of manganese dioxide; this cathode incorporates an inorganic crystalline additive of tungsten oxide, compounds of zirconium, titanium oxide with rutile structure, yttrium oxide, cerium oxide, zeolites and aluminosilicates, and at least one of these is present in a proportion or range between one ten thousandth (0.0001) and ten (10) percent by weight of the cathode mass.

Abstract: This mini fuel cell battery has a central body into which two membrane electrode assemblies are positioned, one at each end of the central body. An anodic space is defined between the two membrane assemblies. The central body has two internal threads into which two externally threaded rings are screwed in to seal the membrane assemblies in the central body.

Abstract: A consumption battery which utilizes fuel battery technology and preferably complies with the standards of size and voltage of traditional batteries, wherein the consumption battery comprises two independent parts which are separable from one another, consisting of an electric generator unit (2) and a fuel supply unit (3), with the electric generator unit (2) being configured for use, preferably as a permanent or reusable part, with successive fuel supply units (3), and the fuel supply unit (3) being non-reusable or rechargeable after each use.
