Abstract (en)
[origin: WO2006079331A1] The invention relates to a fuel cell system wherein at least one fuel cell (8) is fed with a compressed oxidation gas at least intermittently and/or at least partially. The invention also relates to a method for starting a fuel cell system, said method comprising the following steps: a valve (6) connecting at least one fuel cell (8) to a compressed gas source (1) supplying a compressed oxidation gas is opened; fuel is supplied to the at least one fuel cell (8); it is checked that the fuel cell system has reached an operating point at which sufficient energy for the autonomous operation of the fuel cell system and for the consumers to be supplied is generated; and a discreet or gradual switch is carried out from the supply of a compressed oxidation gas stored in the compressed gas accumulator (1) to the ambient air supplied by a fan (5). The invention also relates to the use of said fuel cell system in an emergency power supply.
