초록

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.
