  • Method and apparatus for monitoring a selected group of fuel cells of a high-temperature fuel cell stack
    Patent number: 6432569
    Abstract: In a method and an apparatus for monitoring a selected group of fuel cells of a high-temperature fuel cell stack, a change over time in an averaged electrical voltage of the fuel cells of the selected group is ascertained and compared with a reference value that detects at least a change over time in a voltage of other fuel cells. The method permits a reliable detection of the failure of one fuel cell of a stack with simple measures.
