Abstract
According to the invention, a method for parallel condensation and evaporation is provided for a fuel cell system with a condensation/evaporation device. In this case, the condensation-evaporation device (KVV) has a condensation chamber and an evaporation chamber, which are thermally coupled to one another via a heat exchanger so that water vapor contained in the condensation chamber in exhaust gas of a fuel cell stack is condensed into water and in the evaporation chamber a liquid fuel of a two-phase mixture comprising the liquid fuel and a gas phase, are at least partially vaporized to fuel vapor. In this case, the energy required for evaporation is at least partially provided by waste heat from an exhaust gas of a fuel cell stack of a fuel cell and the associated energy withdrawal from the exhaust gas of a fuel cell stack is used for condensation. The present invention is characterized in that the gas phase comprises a carrier gas which is CO.
