Title: Compact high temperature electrochemical cell stack architecture

Abstract

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.
