Abstract
The fuel cell system includes a membrane/electrode assembly, a fuel cell stack, an electrical load, a switch, and a control unit. The fuel cell stack includes a plurality of fuel cells, and the electrical load is selectively electrically connectable to the fuel cell stack through the switch which is actuated by a control signal of the control unit, and the control unit is configured to generate a control signal for turning on the switch when a shutdown of the fuel cell stack occurs.
Claims20
A fuel cell system including a membrane/electrode assembly, comprising:
- fuel cell stack including a plurality of fuel cells;
- an electrical load selectively electrically connectable with said fuel cell stack;
- a switch configured to selectively connect said electrical load to said fuel cell stack;
- and
- a control unit configured to generate a control signal for actuating said switch, said control unit generating a control signal for turning on said switch when a shutdown of said fuel cell stack occurs.
