A fuel cell system has an anode space and a cathode space which are separated from one another by a proton-conducting membrane, and an oxygen-containing gas flows through the cathode space. According to the invention, it is suggested to admit to the anode space a liquid fuel/coolant mixture, preferably a methanol/water mixture. By means of this combination of the fuel circulation and the coolant circulation, the system can be manufactured in a more compact and lower-cost manner.
[ What is claimed is:] [1.] A fuel cell system having an anode space and a cathode space which are separated from one another by a proton-conducting membrane, a cathode feed pipe for feeding oxygen-containing gas to the cathode space, an anode feed pipe for feeding a liquid fuel/coolant mixture to the anode space, a return pipe between the anode space output and the anode feed pipe, a first gas separator arranged in the return pipe with a pertaining first outlet pipe for removing separated gas and a cathode exhaust gas pipe, wherein:a cooler and a second...
