Abstract

A fuel cell system comprises a combination of a first fuel cell of a first type and a second fuel cell of a second type, arranged downstream of the first fuel cell. The anode side of the first fuel cell is coupled with a cathode side of the second fuel cell; allowing the purge gas emanating from the first fuel cell to be fed to the cathode side of the second fuel chamber, rather than to outside air.
