Abstract

The invention relates to a method for diagnosing a fuel cell arrangement which comprises a plurality of fuel cells arranged in a fuel cell stack (10) for one or more operating parameters to be monitored. Said method comprises the following steps: subdividing the fuel cell stack (10) into a number of packets (G601, G602,... G607) containing a plurality of fuel cells, and detecting the operating parameter (n1 i, n2 i,... n7 i) to be monitored in regular intervals on every packet (G601, G602,... G607) of the fuel cell stack (10). The method according to the invention is characterized by the following steps: comparing the course of the detected operating parameters (n1 i, n2 i,... n7 i) to the course of the average value of the detected operating parameters (n1 i, n2 i,... n7 i) and producing an alarm signal if the result of the comparison infringes a predetermined condition, and/or forming a time average of the detected operating parameters (n1 i, n2 i,... n7 i), comparing the course of the time averages (m1 to m7) to the course of the time averages of the average readings, and producing an alarm signal if the result of the comparison infringes a predetermined condition.
