Abstract

See full text

A method for operating a fuel cell system comprising a control unit and at least one fuel cell comprises a cycle of the following steps: recording of an actual U/I characteristic curve of the fuel cell, comparison of the recorded actual U/I characteristic curve of the fuel cell with a target U/I characteristic curve stored in a memory, at least within a predetermined or pre-determinable current range, and determination of the difference between the target U/I characteristic curve and the actual U/I characteristic curve within the current range, comprising the following steps: continuous or clocked repetition of the cycle until the difference reaches or exceeds a predetermined or pre-determinable difference limit value, and adjustment of at least one parameter of the control unit to reduce or minimize the difference.
