Problems solved by technology

[0003] At present, the reformer, burner, heat exchanger, and steam generator are independently designed. When integrated in the combined heat and power system, the above components occupy a large amount of space, which is not conducive to the compactness of the combined heat and power system, and also increases system cost
In addition, the development of the solid oxide fuel cell industry is not yet sufficient, and the upstream and downstream industrial chains have not been fully connected. The development of combined heat and power systems first needs to solve the design and preparation of reformers, burners, heat exchangers, and steam generators. , which to some extent limits the development of the solid oxide fuel cell industry

Description

technical field [0001] The invention relates to the technical field of fuel cells, in particular to a thermal component used in a solid oxide fuel cell system and a preparation method thereof. Background technique [0002] The solid oxide fuel cell is a device that can efficiently convert the chemical energy of the fuel into electrical energy. The power generation efficiency can reach more than 60%. Household natural gas is very suitable for household power supply and heating. The main component of natural gas is methane, so when using natural gas for cogeneration of heat and power, it is necessary to reform the methane in natural gas into hydrogen and carbon monoxide, and the efficient reforming reaction needs to absorb a large amount of heat and water vapor, so in order to improve the fuel And heat utilization rate, combined heat and power system needs to include reformer, burner, steam generator and multiple heat exchangers. [0003] At present, the reformer, burner, he...
