Abstract:
1. 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, a distributor structure for each of the at least one fuel cell coupling the cathode inflow line to at least two different locations of the cathode region, a humidifier being arranged in the anode inflow line, the humidifier having a first inflow port and a second inflow port and a first outflow port and a second outflow port for two mass flows separated by a membrane, the membrane being essentially only permeable to water or water vapor, the first inflow port communicating with a fuel source, the first outflow port in fluid communication with the first inflow port, the first outflow port being connected to the anode inflow line, the second inflow port connected to the cathode outflow line, and the second outflow port in fluid communication with the second inflow port and being connected to the junction.
