Embodiment Construction
[0033] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0034] figure 1 A control device for water vapor in a solid oxide fuel cell test application is shown, including a water tank 1 connected through pipelines, a first temperature sensor 2, a second pressure sensor 3, a metering pump 4, and a first one-way valve 5 , evaporator 6, mixer 7, heater 8, heating belt 9 and gas flow controller 10, second temperature sensor 11, second pressure sensor 12, third temperature sensor 13, second one-way valve 14.
[0035] The water tank 1 is filled with liquid distilled water, and the metering pump 4 is used to adjust the flow of liquid water. The outlet of the water tank 1 is connected to the inlet of the metering pump through a pipeline. The first temperature sensor 2 and the first pressure sensor 3 are arranged at the outlet of the water tank and the metering pump. The pipeline between the inlets is used t...

The invention relates to a device and a method for controlling water vapor in an application of testing a solid oxide fuel cell. The device comprises a water tank, a metering pump, a first one-way valve, an evaporator, a gas flow controller, a second one-way valve, a mixer, a heater and a heating tape, wherein the water tank, the metering pump, the first one-way valve, the evaporator and the mixer are connected in sequence; the gas flow controller, the second one-way valve and the mixer are connected in sequence; the mixer and the evaporator are placed in a heating cavity of the heater; a pipeline between the outlet of the water tank and the inlet of the metering pump is provided with a first temperature sensor and a first pressure sensor; the mixer is provided with a second temperature sensor and a second pressure sensor; and a fuel gas inlet pipe is provided with a third temperature sensor. Compared with the prior art, the method and the device have the advantages of leading the control and measurement for the water vapor to be more convenient and more accurate without a humidity measurement device and considering the influence of temperature and pressure to the volume of the water vapor, and are suitable for high pressure environment.
Description
technical field [0001] The invention relates to a water vapor control device and method in solid oxide fuel cell testing applications. Background technique [0002] Hydrogen energy is an ideal clean energy, and fuel cells are the best way to efficiently convert hydrogen energy into electrical energy. But at present, the main source of hydrogen is still hydrocarbons (such as natural gas reforming), and this process of obtaining hydrogen will inevitably produce CO2; at the same time, considering factors such as cost, technology and social acceptance, the era of hydrogen energy is still far away. did not come. This has also become one of the important reasons for limiting the promotion and use of hydrogen fuel cells. Not all fuel cells must use hydrogen as fuel. Solid oxide fuel cells (SOFC) work at high temperatures (600-800°C), and can use cheap hydrocarbons (such as natural gas, etc.) as fuel. Although there is carbon dioxide in its reaction product, SOFC has huge potent...
