Abstract
The invention relates to a fuel generator (12) for a fuel cell based charger system, and a system containing a charger (10) and a fuel generator. The generator comprises a compartment (20′) containing aluminium, means (18′, 20′, 21, 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…
