Proton exchange membrane water electrolyser and assembling device and manufacturing method thereof

According to the proton exchange membrane water electrolyser provided by the invention, the proton exchange membrane water electrolyser has a very good sealing effect by arranging the sealing gaskets among a plurality of components, and meanwhile, the problem that the components of the existing proton exchange membrane electrolyser are inconvenient to replace after being assembled is solved. The invention provides the assembling device and the manufacturing method of the proton exchange membrane water electrolyser, so that the assembling process of the proton exchange membrane water electrolyser is convenient, and a pipeline of a water electrolyser test board and a direct-current power supply cable can be directly connected on the assembling device to carry out an electrolytic performance preliminary test without applying an assembling component for fastening after assembling and pressing; therefore, whether each part meets the electrochemical performance of the electrolytic cell design or not is detected, an
