Conditioning device (10) for a fuel
cell system (12) with at least one fuel
cell, wherein the conditioning device (10) serves both to humidify and to temperature-control a first material
stream (20, 22), wherein a first unit (41) serves to temperature-control the first material
stream (20, 22) and a second unit (45) primarily serves to humidify the first material
stream (20, 22), and the first unit (41) and the second unit (45) together form a
building unit (40), wherein the first material stream (20, 22) is a
cathode or
anode input stream (20, 22), in particular the
cathode input stream (20), and a second material stream (21, 23, 24) for
heat transfer in the first unit (41) is a
cathode or
anode output stream (21, 23) or at least a partial stream of a
coolant stream (24) which is in a cooling
system (30) of the fuel
cell system (12) is manageable, and a third material stream (21,23,24) for the release of
moisture in the second unit (45) is a cathode or
anode output stream (21, 23) or at least the partial stream of the
coolant stream (24), characterized in that a
heat exchanger (49), in particular a further
shell and tube heat exchanger, is arranged in the first unit (41), wherein the
heat exchanger (49) serves for
temperature control, in particular for cooling, at least one partial stream (24.1, 25.1) of the second
mass stream (21, 23, 24) by the third
mass stream (21, 23, 24).
