| 摘要 |
<p>The invention relates to a fuel cell system comprising an anode chamber (2) and a cathode chamber (3), which are separated from one another by a proton-conductive membrane (4). A gas containing oxygen flows through the cathode chamber. A liquid fuel/coolant mixture, preferably a mixture of methanol and water is guided in a circuit through the anode chamber. To provide greater frost-protection and improved cold-starting capability, a temperature in the fuel cell system is monitored, even when said system is at a standstill and if a drop in temperature occurs, the concentration of fuel in the anode circuit is increased.</p> |
