Fuel cell system comprising at least one fuel cell

摘要

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.

1. A fuel cell system, comprising:
a fuel cell; a circulation system configured to circulate anode exhaust gases of the fuel cell around an anode region; a line element carrying process air flow to a cathode inlet of the fuel cell, wherein the line element extends from a lower position into an upper position arranged higher when used in a direction of gravity, wherein the process air flow occurs from the lower position to the upper position; and a drain line arranged in the circulation system and configured to supply liquid and gas from a region of the circulation system into the line element, wherein the drain line is connected to the line element in such a manner that fuel in the anode exhaust gases passes from the drain line, to the upper position of the line element, and into the cathode inlet.
