[0002] Current water electrolysis hydrogen production technologies are mainly divided into three categories based on the different electrolytes: alkaline water electrolysis hydrogen production technology, solid oxide water electrolysis hydrogen production technology, and proton exchange membrane (PEM) water electrolysis hydrogen production technology. The working principle of proton exchange membrane water electrolysis hydrogen production technology is that water enters the electrolytic cell from the anode side, is electrolyzed at the anode to produce oxygen and protons, and the protons are conducted to the cathode through the proton membrane. At the cathode, they undergo a reduction reaction with electrons transmitted from the external circuit to produce hydrogen. The hydrogen production module is composed of a proton membrane disposed between the anode plate and the cathode plate. Since the hydrogen production effect is mainly affected by the hydrogen production module, it is necessary to test the hydrogen production effect of the hydrogen production module. When testing the hydrogen production module, it is necessary to apply a loading force to it to tightly clamp the anode and cathode plates. The loading pressure of the existing hydrogen production module relies on mechanical pressure of the thread, such as the membrane electrode testing device disclosed in patent publication number CN218412727U. However, there are problems such as uneven loading force applied to the hydrogen production module, uncertainty of the applied loading force, inconvenience in operation, and poor test accuracy of the hydrogen production effect of the hydrogen production module.
