Abstract (en)

[origin: DE19807876A1] A fuel cell system has an anode chamber (12) and a cathode chamber (14) which are separated by a proton- conducting membrane (16). There is a cathode supply line (20) for oxygen-containing gas to the cathode chamber and an anode line for the supply of a liquid coolant/fuel mixture to the anode chamber. The anode chamber is located in an anode circuit comprising a radiator 946), a gas separator (52) and a pump (34). A cooling of the coolant/fuel mixture circulating in the anode circuit takes place by the fuel cell which is designed for an operation with water penetration from the anode chamber into the cathode chamber
