Abstract

The invention relates to devices for operating fuel cells. According to the invention, the two functions “cooling” and “humidification” are combined in a functional unit (10) to adjust the temperature of the air (1) supplied as the reaction medium and to humidify it. Membranes (5) are used that consist of a temperature-resistant material.
