A fuel cell system () includes at least one fuel cell () provided with an anode area () and a cathode area () which is separated from the anode area () by an electrolyte () and a first liquid separator (). A liquid out () of the first liquid separator () is connected to a second liquid separator () or cathode gas discharge line () via a first bypass line ().

Fuel cell system with a liquid separator

A method and apparatus are provided for regulating electrical power output of a fuel cell system comprising a fuel processing system, a system for supplying an oxidant stream, and a fuel cell to supply power. In a reformer of the fuel processing system a supply fuel is used to produce hydrogen-rich gas to be supplied to the fuel cell. The fuel cell system also contains a controller to set the mass flow of the supply fuel to the fuel processing system and the mass flow of the oxidant stream to the fuel cell, whereby the mass flow of the oxidant stream can be set in dependence on the dynamic response of the fuel processing system and/or the mass flow of the hydrogen-rich gas can be set in dependence on the dynamic response of the system for supplying the oxidant stream.

Method and apparatus for regulating electrical power output of a fuel cell system

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.
