Abstract
A high-temperature fuel cell system having a particularly simple construction and a particularly low power requirement for a compressor on the air side, includes at least one high-temperature fuel cell stack being disposed in a container and forming a partition or part of a partition separating an air entry space into which air inlets of high-temperature fuel cells open, and an air exit space into which air outlets of the high-temperature fuel cells open, from one another in gas-tight fashion in the container. Preferably, at least one location in the partition is provided at which the air situated in the air exit space can be recirculated at least partially into the air entry space through the use of air flowing into the air entry space. The effect achieved thereby is that the compressor compresses cold, relatively dense air and a recirculation of hot air in the container can be carried out without the use of moving parts.
