Abstract
A method is used to start up a fuel cell electrically in a fuel cell installation, especially a fuel cell for use in a motor vehicle, with a gas-generating system producing a hydrogen-containing gas flow. The gas flow from the gas-generating system and an oxygen-containing gas flow are brought together and combusted after the fuel cell. The fuel cell is started up electrically as a function of a temperature course existing in the region of combustion of the gas flows.
Claims16
A method for starting up a fuel cell electrically in a fuel cell installation, comprising:
- combining a hydrogen-containing gas flow from a gas-generating system and an oxygen-containing gas flow downstream of a fuel cell;
- combusting the combined gas flows;
- and
- starting up the fuel cell electrically as a function of a temperature existing in a region of said combusting of the combined gas flows.
1 more element
An fuel cell system, comprising:
- a fuel cell having an anode space and a cathode space;
- a gas-generating system;
- a catalytic burner downstream of the fuel cell in which air from the cathode space and hydrogen-containing gas from the anode space are combusted;
- a temperature sensor downstream from the catalytic burner;
- a bypass line from the gas-generating system past the fuel cell;
- and
- a control and regulating system for electrically starting up the fuel cell in response to a signal from the temperature sensor.
