摘要

The fuel cell system has a fuel cell (10) with at least one air inlet and waste gas outlet, a gas compressor (11) connected to the air feed line (12) carrying process air from the compressor to the fuel cell, a recovery unit (15) in the waste gas line (13), a liquid-gas separator unit (14) between the cell and recovery unit with a storage container (14b) for separated water, a water feed line (20) between the storage container and compressor and a pressure feed arrangement for using the waste gas pressure to force the stored water into the water feed line.
