| 摘要 |
The invention relates to a method for detecting a critical concentration of hydrogen in the exhaust gas of a fuel cell system (1), in which exhaust gas from an anode chamber (4) of a fuel cell (3) is subjected to post-combustion by means of a burner (17). The invention is characterised in that the temperature of the combustion exhaust gases is detected, said temperature being compared to a predetermined limit value. In said comparison, if the temperature of the combustion exhaust gases exceeds the limit value, a critical concentration of hydrogen can be assumed. |
