20110223498 | SUPPLY ASSEMBLY FOR COUPLING TO A FUEL CELL DEVICE AND FUEL CELL SYSTEM HAVING THE SUPPLY ASSEMBLY - A supply assembly and a fuel cell system having a supply assembly that demonstrates a cost-effective and/or resilient design in operation. A supply assembly for coupling to a fuel cell device is proposed, having a gas-to-gas humidifier that is designed and/or arranged in order to humidify the oxidation means A for the fuel cell device by means of the humidity from the exhaust gases B of the fuel cell device. The gas-to-gas humidifier has an exhaust gas region and an oxidation means region that are separated from one another by a separation layer. The separation layer enables a transmission of the humidity from the exhaust gas region into the oxidation means region for humidification of the oxidation means A, wherein the gas-to-gas humidifier has a monolithic honeycomb structure for forming the exhaust gas region and the oxidation means region. | 09-15-2011 |
