Fuel Cell System Comprising at Least One Fuel Cell

9:

• A fuel cell system comprising:
• at least one fuel cell including a cathode region and an anode region, the cathode region having a cathode inflow line and a cathode outflow line and the anode region having an anode inflow line and an anode outflow line, a junction of the anode and cathode outflow lines being provided downstream of the anode region and the cathode region, the junction being in fluid communication with a first region, the first region including a catalytically active material with respect to a reaction of a fuel for the fuel cell with an oxidant for the fuel cell, the cathode inflow line being in fluid communication with the cathode region, in each of the at least one fuel cell at least two different locations, and a humidifier being arranged in the anode inflow line.

10:

• The fuel cell system as recited in claim 9 wherein the first region is in fluid communication with a fluid flow machine.

11:

• The fuel cell system as recited in claim 9 wherein an active surface of the anode region is reduced from the anode inflow line in the direction of the anode outflow line.

12:

• The fuel cell system as recited in claim 9 wherein the humidifier has inflow ports and outflow ports for two mass flows separated by a membrane, the membrane being essentially only permeable to water or water vapor.

13:

• The fuel cell system as recited in claim 12 further comprising an inflow port communicating with a fuel source, an outflow port in fluid communication with the inflow port, the outflow port being connected to the anode inflow line, an other inflow port connected to the cathode outflow line, and another outflow port in fluid communication with the other inflow port and being connected to the junction.

14:

• The fuel cell system as recited in claim 13 wherein the fuel source is a hydrogen storage tank.

15:

• The fuel cell system as recited in claim 9 wherein an oxidant is able to be supplied through the inflow line via a pump-type device to the cathode region.

16:

• The fuel cell system as recited in claim 15 wherein the oxidant is air.

17:

• The fuel cell system as recited in claim 15 further comprising a heat exchanger traversable by the oxidant and, by at least one waste gas streaming to the first region, the heat exchanger being arranged between the pump-type device and the cathode region, the oxidant being compressed oxidant.
