Description
Technical Field
The invention relates to a fuel cell and gas turbine hybrid power system combined with solar power generation, and belongs to the technical field of airship power.
Background
The flying height of the high-altitude airship is generally 10 km-30 km. At this altitude, the aircraft is well suited to perform reconnaissance, surveillance, early warning, communication, etc. tasks on the ground. Meanwhile, the airship has the characteristics of long voyage time, long air-leaving time and the like, and the air-leaving time is more than several months, even as long as 1 year. Therefore, the development of airship technology is of great significance to both military and civil fields.
The energy source of the high-altitude airship has three modes: (1) self-contained stored energy sources; (2) an environmental energy source; (3) the self-contained stored energy and environmental energy are combined. The self-contained stored energy source may be fuel oil, nuclear energy, or hydrogen. The fuel oil has the advantages of convenient material acquisition, low price and the like, but the energy density is limited, and the long-time running is difficult to support. The energy density of the nuclear energy used is very high, but there is a radiological risk. The use of hydrogen has the advantages of cleanness, green color and the like, but the limited hydrogen still has difficulty in maintaining the airship for a long idle time. The environmental energy source may be solar energy. Solar energy is a good clean energy source, and has no chemical emission, no redundant heat emission and no carbon emission. Simultaneously, use solar energy to have the inexhaustible advantage, be fit for airship long-time work. However, the solar energy is very dispersed and can be obtained mainly within 10 hours between 8:00 and 18:00, and the obtained energy is difficult to maintain for the rest 14 hours after meeting the flight propulsion requirements of the airship during the 10 hours. The self-contained stored energy and environmental energy combined energy becomes the energy selection of the actual flight propulsion of the airship, and the reliability and the emergency capacity of the energy system are improved. When one of the energy systems fails, the other energy system can reduce the load, reduce the time for operation or provide conditions for emergency landing of the airship. The fuel cell gas turbine hybrid power system combined with solar power generation fully integrates environmental energy and self-contained stored energy, has the characteristics of high efficiency, low emission and the like, and can meet the requirement of long-term flight of the airship.
The SOFC has the advantages of high efficiency, high power density, simple structure, wide fuel adaptability and the like. The conventional SOFC generally separates fuel from oxidant gas by two gas chambers, and can maintain a high chemical potential gradient between cathode and anode to achieve high power generation efficiency and high fuel utilization rate, but the conventional SOFC has the disadvantage of non-uniform cathode and anode gas flow, which may cause non-uniform cell operating temperature, so that thermal stress exists in the cell during operation, which is likely to cause accelerated cell performance degradation. Moreover, conventional SOFCs typically have an additional combustion chamber at the outlet, using fuel that is not electrochemically utilized. This adds to the mass of the overall system, which is very disadvantageous for the airship's power system. Therefore, the fuel cell gas turbine hybrid power system combined with solar power generation provides a solid oxide fuel cell with a uniform flow internal combustion chamber, and can well solve the problems of the traditional SOFC.
