METHOD FOR OPERATING A PEM FUEL CELL INSTALLATION AND PEM FUEL CELL INSTALLATION

摘要

The present invention relates to a method for operating a PEM fuel cell installation (2) containing at least one PEM fuel cell block (4), to which a torque-controlled compressor (8) is series connected for supplying the air volume flow VL. In order to adjust the electric current (I) of the PEM fuel cell block (4) to a set value ISN, the torque n of the compressor (8) is regulated to a theoretical value nSN, whereby said value nSN is derived from the preset value ISN of the electric current, thereby ensuring easy control of the air volume flow VL to the PEM fuel cell block (4) with few industrial devices.
