Abstract
A polymer electrolyte membrane fuel cell system uses a wetting and/or cooling with a liquid medium. A liquid distributor is provided in one or both axial process gas supply lines. The liquid distributor uses acoustic waves for producing droplets directly in front of the gas inlet of each fuel cell unit of a fuel cell stack and feeds the droplets to the process gas flow.
