摘要

The arrangement has a humidifier (24) for moistening an oxidant for a fuel cell stack (12) of a fuel cell system (10), and a by-pass line (30) for bypassing the humidifier. An adjustment device (32) partially locks or releases the by-pass line. An expansion material element (34) actuates the adjustment device and comprises a container (36) that exhibits an expansion material (38), where volume taken by the material is variable based on temperature. The container is partially arranged in a supply air tract of the arrangement. The material element comprises a position element (40). An independent claim is also included for a method for operating a humidification arrangement of a fuel cell system.
