1. A base plate assembly for an electrochemical cell stack, the base plate assembly comprising:
a bottom end plate defining a fuel inlet port, a fuel outlet port, and an oxidant port;
a high strength sealing plate comprising 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;
wherein the tubes are configured to yield to reduce transfer of mechanical stress from the high strength sealing plate to the bottom end plate.
