A device for starting up a fuel cell includes: two valves mounted in the inlet and the outlet of the hydrogen circuit of the anode compartment; and a controlled bridge circuit between the inlet of the hydrogen circuit to the anode compartment and either the anode compartment or the ambient. Thus, the first wing and the second wing of each of the blades co-operate to carry the hot air away from the generator body rapidly, thereby enhancing the heat dissipation effect of the cooling fan. The method may evaluate the performance of each configuration object according to user preferences and may select preferred configuration objects according to a selectable strategy that can, for example, favor unification or diversity in the types of preferred configuration objects.
