Abstract

Systems and methods are provided for fuel cell stack heat treatment. An eductor may be used to recycle air into the air inlet stream or to recycle fuel into the fuel inlet stream. An eductor may also be used to exhaust air away from the furnace. The stack heat treatment may include stack sintering or conditioning. The conditioning may be conducted without using externally supplied hydrogen.
