A base plate assembly for an electrochemical cell stack includes a bottom end plate defining a fuel inlet port, a fuel outlet port, and an oxidant port. The base plate assembly further includes a high strength sealing plate including openings that align with the fuel inlet port, the fuel outlet port, and the oxidant port, and a plurality of tubes located between the bottom end plate and the high strength sealing plate. The tubes are configured to yield to reduce transfer of mechanical stress from the high strength sealing plate to the bottom end plate.

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.

An electrochemical cell unit comprises a first electrochemical cell comprising a first oxidant electrode and a first fuel electrode, and a second electrochemical cell comprising a second oxidant electrode and a second fuel electrode. An interconnect interposed between the first electrochemical cell and the second electrochemical cell. The interconnect comprises an interconnect main body defining a longitudinal channel along a longitudinal axis thereof. The interconnect main body includes a plurality of corrugations defining a plurality of fuel channels on a first surface of the interconnect main body facing the first electrochemical cell, and a plurality of oxidant channels on a second surface of the interconnect main body facing the second electrochemical cell. Each of the plurality of fuel channels and the plurality of oxidant channel positioned around the longitudinal channel.
