Abstract
The application discloses a water electrolysis monitoring control system, which comprises a water electrolysis device, a gas content detection element, a pipeline assembly, a valve assembly and a control unit. The water electrolysis device forms an electrolysis cavity capable of electrolyzing water, and an oxygen output pipeline and a hydrogen output pipeline communicated with the electrolysis cavity, and a proton exchange membrane is arranged in the electrolysis cavity. The gas content detection element is used for detecting the hydrogen content in the gas output by the oxygen output pipeline or the oxygen content in the gas output by the hydrogen output pipeline. The pipeline assembly comprises an exhaust pipeline and an air inlet pipeline. The exhaust pipeline is communicated with the electrolysis cavity to exhaust. The air inlet pipeline is communicated with the electrolysis cavity to input a protective gas into the electrolysis cavity. The valve assembly comprises an exhaust valve arranged in the exhaust pipeline and an air inlet valve arranged in the air inlet pipeline. The control unit is connected with the exhaust valve, the air inlet valve and the gas content detection element respectively, so as to control the exhaust valve and the air inlet valve to be opened according to the detected gas content being greater than or equal to a set value. The present application can avoid the explosion accident caused by the rupture of the proton exchange membrane.
