A fuel cell installation containing a gas generation system, for the production
of a hydrogen-containing gas, and a fuel cell system, which comprises a fuel cell,
a compressor, an expander that is coupled with the compressor and a burner, the
exhaust gases of which are directed to the expander. The gas generation system
and the fuel cell system are designed as independent modules with respect to the
supply of energy and process streams. Energy storage and energy conversion devices
are arranged between the expander and the compressor in the fuel cell system.
