A Solid Oxide Cell (SOC) is a high temperature energy conversion device with high efficiency, no pollution, compact structure, modular design and fuel flexibilityStrong and the like. When operating in a Solid Oxide Fuel Cell (SOFC) mode, chemical energy in hydrocarbon fuel can be directly converted into electrical energy through electrochemical reactions; when operating in Solid Oxide Electrolytic Cell (SOEC) mode, water, CO 2 High-efficiency electrolysis into hydrogen and CO. In general, a single cell can generate limited power, and in order to obtain higher power output, a plurality of single cells need to be connected in series to form a stack. Because of simple structure, lower manufacturing and assembling difficulty and cost, the outflow cavity solid oxide cell stack is considered to be more suitable for large-scale applications such as distributed power generation, hydrogen production and the like.

The outer flow chamber is simpler than the inner flow chamber structure and is less expensive to manufacture and assemble, as disclosed in patent CN201610631780 for an outer flow chamber SOFC stack design, but this design has the following potential. Firstly, the gas pipeline is directly connected with the airflow cavity, and thermal stress acts on the airflow cavity through the pipeline at high temperature, so that the sealing between the airflow cavity and the airflow cavity is invalid, and gas leakage occurs. For this reason, metal bellows are often used between the gas flow chamber and the pipe to relieve thermal stresses, but their application is limited by the high temperature life of the metal bellows. Secondly, the complex gas pipeline around the gas flow cavity of the design increases the difficulty of multi-stack integration, and reduces the volume power density of the electric stack module. In addition, the electric pile airflow cavity is directly connected with the thermal element and the system cold area control module through metal pipelines, and the electric signals of the cold area can influence the collection and transmission of electric pile signals. The above problems jeopardize SOC stack operation, and increase manufacturing costs and assembly difficulties, and the outflow cavity structure is to be further optimized to solve these problems.
