COMPACT HIGH TEMPERATURE ELECTROCHEMICAL CELL STACK ARCHITECTURE

A top compression plate assembly for an electrochemical cell stack includes a top end plate configured to interface with a top end of a stack of electrochemical cells, a top compression plate positioned on the top end plate, and a plurality of springs coupled to a periphery of the top compression plate. The springs are configured to cause the top compression plate to exert a compressive force on the top end plate.
