NOVELTY - A fuel cell data generating system for generating and providing fuel cell data to a processing system, comprises a sensor(s) for providing sensor signals indicative of the fuel cell characteristic to a controller; a controller for determining fuel cell parameter values in accordance with the sensed fuel cell characteristics; and a data bus for providing the fuel cell data from the fuel cell to the processing system.    USE - The system is used for generating and providing fuel cell data to a processing system, i.e. a laptop computer (claimed). It is useful for electronic devices, such as mobile personal computers (PCs), desktop PCs, personal digital assistants, wireless phones, portable media players, portable phones, radios, televisions, test equipment, smart personal objects, digital still cameras, and digital video cameras.    ADVANTAGE - The system reduces the costs and time required to introduce fuel cells into the portable electronic system.    DETAILED DESCRIPTION - A fuel cell data generating system for generating and providing fuel cell data to a processing system, comprises a fuel tank; a fuel cell coupled to the fuel tank for receiving fuel within the fuel tank; a sensor(s) for sensing fuel cell characteristics and for providing sensor signals indicative of the fuel cell characteristic to a controller; a controller coupled to the fuel tank and to the fuel cell for determining fuel cell parameter values in accordance with the sensed fuel cell characteristics; a processing system comprising a fuel indicator, where processing system determines an amount of remaining time for the fuel cell to provide power to an associated computer operating system; and a data bus for providing the fuel cell data from the fuel cell to the processing system, where fuel cell data comprises the determined fuel cell parameter(s), and the controller is coupled to the processing system via the data bus.    DESCRIPTION OF DRAWING(S) - The figure is an illustration of a system for controlling, and reporting data pertaining to, a fuel cell utilizing a gaseous fuel.
