NOVELTY - The consumer battery comprises an electricity generating unit (100) and a fuel carrying unit (200). The electricity generating unit and the fuel carrying unit form a passive tubular fuel cell. The electricity generating unit: is provided with an outer tubular current collector so that the fuel carrying unit supplies a gaseous fuel to the electricity generating unit; and comprises an inner tubular current collector such that parts of the electricity generating unit are arranged between the outer and inner tubular current collectors, and two adjacent electricity generating tubular cells.    USE - Used as a fuel cell consumer battery.    ADVANTAGE - The fuel cell consumer battery is economical to manufacture, and has reduced size and internal resistance, high performance, improved power and storage capacity, and good sealing and electric contact.    DETAILED DESCRIPTION - The consumer battery comprises an electricity generating unit (100) and a fuel carrying unit (200). The electricity generating unit and the fuel carrying unit form a passive tubular fuel cell. The electricity generating unit: is provided with an outer tubular current collector so that the fuel carrying unit supplies a gaseous fuel to the electricity generating unit; comprises an inner tubular current collector such that parts of the electricity generating unit are arranged between the outer and inner tubular current collectors, and two adjacent electricity generating tubular cells connected in series; and applies an outward pressure on the parts arranged between both collectors. An oxidizer is the oxygen in the air. The tubular cells comprise a proton exchange membrane provided, on each side, with a catalyst and a gas diffuser, and two cylindrical seals for sealing the cell and preventing gas leakage, are axially and/or consecutively arranged, and are directly arranged in the same order in the radial direction or inversely arranged in inverse order in the radial direction. The seals are arranged on an outer side and an inner side of the cell. The cylindrical seals are formed during the manufacture of the cell starting from a fluid material that solidifies sealing the cell and preventing gases from entering or exiting the cell or formed during the manufacture of the cell by winding a sheet of a deformable material or pre-formed deformable pieces that provide the sealing of the cells after is pressured. An intermediate current collector is arranged between the inner current collector and the outer current collector, and is shaped as a tubular mesh with two diameters that define two demi-tubes so that a cell is located inside the demi-tube having the larger diameter and the adjacent cell surrounds the outside of the demi-tube having the smaller diameter. An electric contact is established by a bipolar ring arranged between the two concentrical tubular cells. INDEPENDENT CLAIMS are included for:    (1) a method of manufacturing a consumer battery; and    (2) a method of operating a fuel cell consumer battery.
