In a fuel cell system, for example HTPEM fuel cells. a valve system is employed by selectively guiding exhaust gas from the burner either to the reformer for heating the reformer, especially during normal operation, or to by-pass the reformer in startup situations in order to heat the fuel cell stack before starting heating the reformer. Optionally, a compact burner/reformer unit is provided.

Fuel cell system, and method of its operation

A method for increasing safety in the surroundings of an electric vehicle having a fuel cell system and batteries, wherein the vehicle is configured for charging the batteries by power from the fuel cell system and e.g. produces CO2 during this operation, even when the vehicle is turned-off and in a parked situation, wherein the method includes the steps of providing a sensor system having a gas intake and configured for warning against elevated CO2 levels in the surroundings of the vehicle, mounting the sensor system on the vehicle with the gas intake outside the vehicle's cabin, providing an alarm when the sensor system evaluates that the CO2 levels in the surroundings of the vehicle are elevated and surpass a predetermined threshold level.

A fuel cell system () comprising a fuel cell (), a liquid fuel supply () for providing liquid fuel, an evaporator () for evaporating the liquid fuel to fuel vapor, a reformer () for catalytic conversion of the fuel vapor to syngas for the fuel cell and a burner () for heating the reformer (). The burner () comprises a catalytic monolith () down-stream of a mixing chamber () in which air is mixed with evaporated fuel or rest gas prior to entering the monolith (). The mixing chamber () is surrounded by a sleeve (), which comprises a plurality of openings (A,B) around the mixing chamber () for supply of fuel vapor through the openings (A,B) in the startup phase and for supply of rest gas through the openings (A,B) during normal operation. Optionally, a heat exchanger () is provided between the burner () and the reformer () for reducing the temperature of the exhaust gas from the burner () before it reaches the reformer (). This temperature reduction prevents degradation of the reformer () by hot exhaust gas during start-up of the fuel cell system ().

Fuel cell system and method for its operation

A fuel cell system comprising a fuel cell stack, an evaporator for evaporating a mixture of methanol and water to be forwarded through a catalytic reformer for producing portions of free hydrogen. The fuel cell stack being composed of a number of proton exchange membrane fuel cells each featuring electrodes in form of an anode and a cathode for delivering an electric current. The system provides an enhanced system for evaporating the liquid fuel using a pre-evaporator, which partly evaporates the fuel, followed by a nozzle, which atomizes the fuel into a fine mist, before being passed to the final evaporation zone. This configuration ensures minimal fuel accumulation in the system and fast load transition's.
