The solid oxide fuel cell cogeneration and energy storage system is characterized in that the high-temperature exhaust gas generated by the fuel cell after outputting electrical energy enters the heat exchanger, preheating the fuel gas and air supplied to the fuel cell, and also heating the return water entering it for heating; The exhaust gas then drives an ammonia absorption refrigeration system composed of a steam generator, condenser, evaporator, and absorber for refrigeration; Energy storage is carried out through the liquid ammonia storage tanks connected to the liquid ammonia pipeline between the absorber and evaporator, as well as the concentrated ammonia water pipeline between the absorber and steam generator, the concentrated ammonia water storage tanks connected to the dilute ammonia water pipeline, and the dilute ammonia water storage tanks connected to the dilute ammonia water pipeline; Before the exhaust gas is discharged, it can also enter the water recovery device, where the air before entering the heat exchanger is used for condensation to recover water. This system can achieve a combination of heat, electricity, and cooling, with high energy storage density and the ability to recover moisture from exhaust gas. It is easy to miniaturize and air cool, and can increase energy utilization efficiency from 50-80% to 80-92% of solid oxide fuel cells
