Verfahren zum Betreiben einer Brennstoffzellenanlage und Brennstoffzellenanlage

摘要

A process is disclosed for operating a fuel cell system (2) with at least one fuel cell block (4), at least one operating medium for the fuel cell block (4) being compressed by a liquid ring compressor (8). After compressing, water is eliminated from the operating medium by a water separator (10) and is used for cooling the fuel cell block (4). After cooling, at least part of the water is returned to the device (10). This makes it possible to reduce the number of components of the fuel cell system (2).
