NOVELTY - The method of generating electrical power using a power system comprising a fuel cell unit having a fuel cell assembly, a device and a fuel/electrolyte module arranged within a housing arrangement, comprises subjecting the housing arrangement to compression to cause a part of contents of the fuel/electrolyte module to transfer from the module to the fuel cell assembly, gripping and squeezing the housing arrangement to cause the part of contents of the module to transfer from the module to the assembly, and moving two portions of the housing arrangement relative to each other.    USE - The method is useful for generating electrical power using a power system, which is useful in smart phones, camera phones, iPods, MP3, game boys, personal digital assistants, digital cameras and a broad array of military applications.    ADVANTAGE - The method is capable of continuously generating the electrical power using a safe, environmental friendly, lightweight and cost effective power system.    DETAILED DESCRIPTION - The method of generating electrical power using a power system comprising a fuel cell unit having a fuel cell assembly, a device and a fuel/electrolyte module arranged within a housing arrangement, comprises subjecting the housing arrangement to compression to cause a part of contents of the fuel/electrolyte module to transfer from the module to the fuel cell assembly, gripping and squeezing the housing arrangement to cause the part of contents of the module to transfer from the module to the assembly, moving two portions of the housing arrangement relative to each other to cause the part of contents of the module to transfer from the module to the assembly, and removing a safety member acting to prevent the transfer. Before transferring the part of contents of the module, the sealing members of the module are punctured. The fuel cell system is a stand-alone unit, a modular unit, and a portable unit. The fuel/electrolyte module comprises flexible material chambers, separate sealed chambers having a sealed opening, and puncturing members of which each is capable of puncturing the sealing member when the chambers experience a compressive force. The housing arrangement comprises first and second housing parts, which move towards each other. The fuel cell unit comprises a system for delivering, feeding and/or conveying the part of contents of each chamber of the module to an appropriate chamber of the assembly. The fuel cell assembly comprises an anode and a cathode, and the fuel electrolyte module comprises a liquid fuel, a liquid electrolyte and/or components of the liquid fuel and electrolyte. The device in the power system in first position prevents transfer of contents of the module into the fuel cell assembly and in second position allows transfer of contents of the module into the fuel cell assembly. The separate chambers comprise a first chamber for holding a liquid fuel concentrate, a second chamber for holding a liquid for diluting the concentrate, and a third chamber for holding electrolyte, where the liquid fuel concentrate comprises a borohydride compound. The third chamber comprises water. The transferring system comprises opposing surfaces of the parts of housing arrangement, which causes a volume reduction of chambers of the fuel/electrolyte. An INDEPENDENT CLAIM is included for a method of activating a fuel cell system.    DESCRIPTION OF DRAWING(S) - The diagram shows a fuel cell system.
