NOVELTY - The power holster for cellular phone is plastic made, and has a cavity for housing the replaceable fuel tank. A fuel level indicator window is provided in the holder above the fuel tank. Micro fuel cell array is arranged near the fuel tank and is protected over by a variable thickness diffusion mat. The flow tank contains a fuel which is 1:1 molecular ratio of methanol to water.    USE - For portable electronic devices like cellular phone.    ADVANTAGE - Efficient performance, improved workability are enabled with the fuel cell chargers for portable device, which include replaceable fuel cell and blister package. Mass production of the micro fuel cell arrays is enabled with the production of cell array on plastic film in reel to reel process.    DETAILED DESCRIPTION - The micro fuel cell array is a surface replica fuel cell power source. The cellular phone is releasably secured to the power holster by a rachet mechanism. The holder is covered and has a clip for attaching the user's clothing. The holder is provided with fuel tank package and electric contact, for transmitting the power from fuel cell to cellular phone. Similarly, the piggyback charger comprises the fuel cell assembly connected with battery. Ventilation holes are provided in the holder. Similarly the trickle charger has refill port for refueling the fuel tank, with a fuel dispenser. Similarly the portable computer power supply includes the fuel cell housing connected with the computer through a power cord. The micro fuel cell array supplied with the fuel from the fuel tank through tube, which possesses a flow control valve. The fuel cell tank of housing is arranged beneath the keyboard and the micro fuel cell array is backed in the screen. A voltage regulating mechanism is connected to the housing. Hence coupling the miniature fuel cell with portable electrical devices, the new appliance like electric power supply device, desk power changer, battery charger donut are formed.    An INDEPENDENT CLAIM is also included for the manufacturing method of micro fuel cell array, which involves sputtering the electrodes on porous plastic film (7), processed in a vacuum chamber (2). The plastic film web is rolled between the deposition sources (3) and sinks (5), during electrode sputtering. The electrode coated film is then impregnated with electrolyte and heat sealed on its sides. The plastic film coating is performed either by sputtering, evaporation, CVD, spray painting, inkjet painting, xerography, photolithography, or auto electroplating.    DESCRIPTION OF DRAWING(S) - The figure shows the schematic representation of micro fuel cell production vacuum chamber.
