Description
Technical Field
The invention belongs to the technical field of fuel cells, and particularly relates to a solid oxide fuel cell cogeneration system and a cogeneration method thereof.
Background
The solid oxide fuel cell, called SOFC for short, is a device for generating electricity by electrochemical reaction, has no Carnot cycle, and has much higher efficiency than other power generation equipment, and the main products are CO2 and water. The SOFC has the advantages of high power generation efficiency (the self power generation efficiency is close to 60%, the combined use efficiency with a hot gas turbine can reach more than 80%), high combined heat and power efficiency (the waste heat temperature is high between 400 and 600 ℃ and the combined heat and power efficiency is more than 90%), water resource saving (2% of the traditional power generation water consumption), environment friendliness, easiness in modularized assembly, wide fuel selection range (natural gas, coal gas, biomass gas, methanol and the like can be used), no noble metal catalyst is needed, and the SOFC has strong adaptability and has a very high application prospect. SOFC is widely applied, and is mainly applied to the fields of portable power sources, distributed power generation/cogeneration systems, high-performance power sources, large power stations and the like. In recent years, distributed power stations have become an important component of world energy supply due to their low cost, high maintainability and the like. The exhaust temperature of SOFC power generation is very high, has higher utilization value, can not only provide the heat required by natural gas reforming, but also can be used for producing steam, can form combined cycle with a gas turbine, is very suitable for distributed power generation, and has the environmental benefits of high power generation efficiency and low pollution.
One major problem with high temperature solid oxide fuel cells is that the start-up speed is too slow, requiring a long start-up time, which is very inconvenient for some applications. Meanwhile, each time the solid oxide fuel cell is operated again, electric energy is consumed or fuel is combusted, and multiple accumulations have great influence on the utilization rate of the fuel, so that economic loss and accelerated aging of parts are caused to damage the solid oxide fuel cell. The reaction temperature of the solid oxide fuel cell is up to 600-900 ℃, the ambient temperature is only tens of ℃, the temperature rise amplitude is huge in the starting process, and equipment damage and ageing are easily caused by an excessive temperature gradient; at present, the fuel cell stack is heated and started mainly by adopting an electric furnace, and the heating mode mainly comprises the steps of radiating heat to the outer surface of the cell through the radiation heat of a hearth, and then transferring the heat to the inside of the cell through heat conduction.
The heat in the preheating process mainly comes from the radiant heat of the electric furnace to the surface of the battery pack, and the temperature rise in the battery needs to be subjected to a long heat conduction process, so that a large temperature gradient exists in the battery; due to the different thermal expansion coefficients of the materials of the parts of the SOFC, when a temperature gradient exists, the non-uniformity of heating can damage the connection between the parts of the SOFC, and further damage the whole cell and even the cell stack.
