NITROGEN ENRICHED AIR GENERATION AND FUEL TANK INERTING SYSTEM

摘要

A fuel cell power module is used to provide nitrogen enriched air for, in one application, fuel tank inerting in an aircraft. The fuel cell power module has a recirculation line between its cathode side outlet and cathode side inlet. At least one control-lable device is provided to allow the flow rate in the recirculation line to be controlled. The recirculation flow rate is adjusted such Cthat the cathode exhaust has an oxygen concentration useful for inerting a fuel tank or suppressing fire.
