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. |
