ABSTRACT:
A method for identifying a gas leak between anode and cathode gas areas of a PEM fuel cell includes detecting a cell voltage. The anode and cathode gas areas are purged with nitrogen in a first time period. The cathode gas area is filled with oxygen and the anode gas area is filled with hydrogen in a second time period. A drop in the cell voltage below a limit value as a function of time is then measured and evaluated. The method ensures reliable identification of the gas leak. A fuel cell system operating according to the method is also provided.
