Arrangement for monitoring the condition of fuel cell modules

摘要

The subject matter of the invention is an arrangement for monitoring the condition of fuel cells in a fuel cell battery. The fuel cells (8) are connected in at least two parallel-connected rows with the same number of them being connected in series in each of the rows. The rows are split up into the arms of a bridge circuit and are connected to at least one evaluation arrangement (7) which evaluates the voltage or the current picked off between the two arms and produces a fault message and/or switches off the fuel cell battery in the event of any discrepancies beyond acceptable limits.
