The fuel cell system has a reformer (14) for producing a hydrogen-containing gas from a fuel. A fuel cell (12) is arranged at downstream of a burner (16) for thermal conversion of exhaust gases of the fuel cell. A heat exchanger (20) is arranged at upstrea...

The method involves charging batteries (1) of a hybrid system by a power generator (3) i.e. fuel cell, in charging phases, and switching the batteries from one charging phase into another charging phase depending on specific parameters. A load (7) is suppl...
