Description

technical field [0001] The invention relates to an electrochemical energy device, in particular to a battery pack module in which a plurality of single cells are arranged in an array. Background technique [0002] SOFC (Solid Oxide Fuel Cell) power generation technology is one of the next-generation power generation technologies with great potential, which has the advantages of all solid state, high efficiency, and low pollution. The traditional double-chamber SOFC can use various fuels such as hydrogen, methane, coal gas and natural gas, and oxidants such as oxygen. These gaseous reactants are respectively located in the gas chambers on both sides of the electrolyte of the SOFC, and the anode gas chamber is Fuel gas, and oxygen (or air) in the cathode chamber, which is also the basic composition of SOFC. Conventional double-chamber structure SOFC battery packs have been designed in various designs such as flat plate type, conical tube type in series, unsealed tube type, co...
