Description

technical field [0001] The invention relates to the technical field of battery assembly, in particular to a vertical assembly device and method for a molten carbonate fuel cell stack. Background technique [0002] Molten Carbonate Fuel Cell (Molten Carbonate Fuel Cell, MCFC) is a high-temperature fuel cell that works at 650°C. It has the advantages of high efficiency and can realize cogeneration of heat and power. It is suitable for hundreds of kilowatts to megawatts distributed power stations or fixed power stations, and has good development prospects. [0003] The molten carbonate fuel cell works at 650°C. The structure of MCFC can be divided into four parts: cathode, electrolyte, anode, and bipolar plate. The electrolyte system of MCFC is composed of a porous diaphragm carrier and carbonate. The molten carbonate electrolyte relies on capillary force to fill the pores of the electrolyte diaphragm, and the carbonate electrolyte is fixed in the diaphragm carrier to form an ...
