Abstract
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.
