摘要：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.

主权项：1. A method for heating a fuel cell stack, comprising: placing the fuel cell stack in a furnace, wherein the furnace comprises: a heat source;a base configured to support the fuel cell stack; andan eductor; operating the furnace to at least one of sinter or condition the fuel cell stack; and providing cooler, higher pressure air from an air input into a motive inlet of the educator to draw lower pressure, warmer air from the fuel cell stack through a suction inlet of the educator.
