Electric power is produced in a fuel cell array based on chemical fuel provided from a fuel source. The electric power is held available via an output terminal. A sensor cell registers a sensor signal reflecting a degree of consumption of chemical fuel in the fuel cell array relative to an amount of chemical fuel received in the fuel cell array. The production of electric power in the fuel cell array is monitored by measuring at least one voltage in the fuel cell array. A fraction of the electric power produced by the fuel cell array is controlled to be fed into a dynamic electric load connected to the output terminal. The fraction fed into the dynamic electric load is controlled in response to the sensor signal such that a difference is minimized between the amount of chemical fuel received in the fuel cell array and an amount of chemical fuel consumed in the fuel cell array when producing the electric power.

System and method for generating electric power with a fuel cell array, control unit and dynamic electrical load

The invention relates to a fuel generator () for a fuel cell based charger system, and a system containing a charger () and a fuel generator. The generator comprises a compartment (') containing aluminium, means (, FW) for providing a solution of water and a water soluble compound capable of reacting with aluminium to generate hydrogen gas, when dissolved in water and brought into contact with the aluminium, and means (FS) for passing said solution into the compartment containing aluminium. The invention also provides a method of operating the system. It comprises providing a fuel generator and a hydrogen driven fuel cell based charger device having means for accommodating the generator. The generator and charger having a common interface cooperative for providing fluid communication between the generator and the charger. The system is primed by inserting the generator into the charger whereby the interface opens up fluid communication between selected parts of the system. A flow of reaction solution is initiated so as to bring it into contact with the aluminium whereby hydrogen begins to be produced, the hydrogen is fed to the fuel cells in the fuel cell assembly whereby electricity is produced.
