Abstract
An apparatus for recirculation of a cathode gas in a fuel cell arrangement having a cathode gas supply for supplying the cathode gas to a cathode area, and a cathode gas outlet for carrying the partially consumed cathode gas out of the cathode area, includes a recirculation line for recirculation of the partially consumed cathode gas from a junction point in the cathode gas outlet into a supply point in the cathode gas supply. Blocking apparatus is provided to block the cathode gas supply in the flow direction upstream of the supply point and to block the cathode gas outlet in the flow direction downstream from the junction point, such that a closed circuit for the partially consumed cathode gas is formed when the blocking apparatus is closed.
