System and methods for refurbishing fuel cell stack components, the methods including singulating the stack using a splitting apparatus or a liquid nitrogen bath. Fuel cell debris may be removed from interconnects of the fuel cell stack using laser heating, flame heating, a die, sonication, a nubbed roller, grit blasting, and/or a high pressure fluid.

Systems and methods for recycling fuel cell stack components

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.
