20120007370 | Fuel Cell System Comprising at Least One Fuel Cell - A fuel cell system includes a fuel cell with a cathode region and an anode region. The fuel cell system also includes at least one device, which is flown through by an intake air flow flowing to the cathode region and by a used air stream discharged from the cathode region. It also includes catalytic material for the thermal conversion of fuel-containing gas. A first unit with catalytic material is arranged in the flow direction of the intake air flow upstream the at least one device. An exhaust gas from the anode region can be fed to this first unit as a fuel-containing gas. A second unit with catalytic material is arranged in the flow direction of the used air flow downstream of the at least one device. | 01-12-2012 |
20120007371 | Fuel Cell System Comprising at Least One Fuel Cell - A fuel cell system comprises a fuel cell with a cathode region and anode region. The fuel cell system includes an exchanging device, which is flown through by an intake air flow flowing to the cathode region and by a used air flow discharged from the cathode region. In the exchanging device, heat is transferred from the intake air flow to the used air flow, and water vapor is simultaneously transferred from the used air flow to the intake air flow. At least part of the exchanging device is provided with a catalytic material at the intake air side. Furthermore, an exhaust gas from the anode region is fed to the exchanging device at the intake air side. | 01-12-2012 |
20120040258 | Fuel Cell System Comprising at Least One Fuel Cell - A fuel cell system includes a fuel cell with cathode and anode regions. The fuel cell system also includes an exchanging device through which an intake air flow flows to the cathode region and a used air flow is discharged from the cathode region. In the exchanging device, heat is transferred from the intake air flow to the used air flow, and water vapor is simultaneously transferred from the used air flow to the intake air flow. A compressor is arranged downstream of the exchanging device to receive used air. A catalytic material is arranged upstream of the turbine, to which material can be supplied a fuel-containing gas. The catalytic material is integrated into the exchanging device on the used air side and an exhaust gas from the anode region is supplied to the used air side of the exchanging device. | 02-16-2012 |
20130137004 | Device for Humidifying Anode Gas - A device for moistening an anode chamber of a fuel cell and/or a gas flow to the anode chamber of the fuel cell includes a water separator in an exhaust gas flow from the anode chamber and a moistening device for supplying at least a part of the water to the anode chamber and/or to the gas flow flowing to the anode chamber. The water separator and the moistening device are connected via a line element. The water separator is pressurized so that the pressure in the region of the water separator can be increased at least temporarily over the pressure in the region of the moistening device. The pressurization takes place by means of a gas, whereby a valve is arranged in the gas flow flowing to the anode chamber. | 05-30-2013 |
