FUEL CELL SYSTEM AND METHOD FOR STARTING A FUEL CELL SYSTEM
摘要
The invention relates to a method for starting a fuel cell system comprising a reformer (10) and a fuel cell stack (12). Oxygen and fuel having a first air ratio ?<SUB>1</SUB> characterising the fuel-air ratio are supplied to the reformer during a first start phase. Oxygen and fuel having a second air ratio ?<SUB>2</SUB> characterising the fuel-air ratio are supplied to the reformer during a second start phase. The first air ratio ?<SUB>1</SUB> is greater than the second air ratio ?<SUB>2</SUB> (?<SUB>1</SUB> > ?<SUB>2</SUB>) and reformate (18) produced during the first and the second start phase is supplied to the fuel cell stack. According to the invention, the transition from the first start phase to the second start phase is monitored by the detection of a electrical voltage supplied by the fuel cell stack. The invention also relates to a fuel cell system.
