FUEL CELL STACK COLUMN INCLUDING STRESS-RELIEF COMPONENTS

摘要

A fuel cell column includes termination plates, fuel cell stacks disposed between the termination plates, and fuel manifolds disposed between the fuel cell stacks. The fuel cell stacks include fuel cells, interconnects disposed between the fuel cells, and end plates disposed on opposing ends of the fuel cell stacks. At least one of the termination plates and/or the fuel manifold may include first and second separate pieces separated by an expansion zone. The fuel cell stack may also include one or more buffer layers and/or seals configured to reduce CTE differences of components of the fuel cell stack.
