Abstract (en)
[origin: DE19821766C1] The invention relates to a PEM (polymer electrolyte membrane) fuel cell system with humidification and/or cooling with a liquid medium, especially for use in mobile systems. A liquid distributor is provided in one or both axial process gas supply lines. With the help of sound waves, said liquid distributor produces droplets immediately in front of the gas inlet of each fuel cell unit of a fuel cell stack and adds these to the stream of process gas (cf. an ink jet printer).
