Abstract
Es wird ein Brennstoffzellensystem mit wenigstens einem Brennstoffzellenstack (10) vorgeschlagen, der eine Anodenseite (12) aufweist, der über ein Anodensystem Brennstoff zugeführt wird und der eine Kathodenseite (14) aufweist, der über ein Kathodensystem Luft zugeführt wird. Das Kathodensystem weist wenigstens einen Luftverdichter (20) auf, durch den verdichtete Luft zur Kathodenseite (14) gefördert wird. Dem wenigstens einen Luftverdichter (20) wird gasförmiges Kühlmedium, insbesondere Luft, zugeführt, das nach Durchströmung des Luftverdichters (20) aus diesem durch wenigstens einen Auslass (52) austritt. Das Brennstoffzellensystem weist wenigstens eine Komponente (42, 44) auf, in der maximal Umgebungsdruck herrscht. Der wenigstens eine Auslass (52) des wenigstens einen Luftverdichters (20) ist mit der wenigstens einen Komponente (42, 44) verbunden.A fuel cell system is proposed with at least one fuel cell stack (10) which has an anode side (12) which is supplied with fuel via an anode system and which has a cathode side (14) which is supplied with air via a cathode system. The cathode system has at least one air compressor (20) through which compressed air is conveyed to the cathode side (14). The at least one air compressor (20) is supplied with a gaseous cooling medium, in particular air, which, after flowing through the air compressor (20), exits it through at least one outlet (52). The fuel cell system has at least one component (42, 44) in which the maximum ambient pressure prevails. The at least one outlet (52) of the at least one air compressor (20) is connected to the at least one component (42, 44).
