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 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 fowling the exhaust gas region and the oxidation means region.

Supply assembly for coupling to a fuel cell device and fuel cell system having the supply assembly

The invention relates to a fuel cell stack () of a fuel cell system that is to be hermetically sealed off from the environment after operation is ended so that only a finite amount of air oxygen remains in the fuel cells, thus preventing the fuel cells from excessively aging. According to the invention, locking means () are provided that are disposed on or in an end plate () or distributor plate of the fuel cell stack (). The locking means () are therefore thermally coupled to the end plate () and may freeze up at cold ambient temperatures. In a preferred embodiment, the locking means () comprise an elastomer body () able to cover and uncover a channel () in the plate ().
