Abstract

A fuel cell system includes at least one fuel cell and a circulation system for anode exhaust gases of the fuel cell around an anode region. The fuel cell system also includes a drain line for feeding liquid and water from the region of the circulation system into a process air flow to a cathode region of the fuel cell. The drain line opens into a line element for the process air flow which runs from a lower position into an upper position arranged higher when used properly in the direction of gravity. The flow of the process air runs from the lower position to the upper position of the line element.
