Embodiment 1

[0029] see Figure 1-6 As shown, a PEM electrolytic cell includes an electrolytic cell 1 and a bottom plate 2. The electrolytic cell 1 is located directly above the bottom plate 2. The electrolytic cell 1 is cushioned with a layer of PEM film 101 with a uniform thickness. The PEM film 101 is a proton exchange membrane. The membrane 101 works at high current density in the process of hydrogen production from pure water in electrolyzer 1, with small volume and high efficiency, and the purity of the generated hydrogen can be as high as 99.999%, which can effectively ensure the high purity of hydrogen produced from pure water. 1. The lower side wall and the upper side wall of the bottom plate 2 are fixedly connected by multiple groups of evenly distributed telescopic columns 3, each telescopic column 3 is sleeved with a corresponding spring 4, and both ends of the spring 4 are respectively connected to the lower side of the electrolytic cell 1. The wall and the upper side wall of ...

Embodiment 2

[0034] see Figure 7 As shown in the comparison example 1, as another embodiment of the present invention, a plurality of groups of evenly distributed positioning protrusions 40 are fixedly arranged on the side of the splint 7 close to the unit slot main body 6, and the unit slot main body 6 is provided with The positioning grooves 41 matched with the protrusions 40 are used in conjunction with the positioning protrusions 40 and the positioning grooves 41 to improve the stability of the splint 7 in the installation of the unit groove main body 6 and ensure that the clamping plate 7 is fixed to the unit groove main body 6 after the fixed installation. The unit cell main body 6 does not move.

[0035] Working principle, as the hydrogen production from pure water in the electrolytic cell 1 continues, the content of pure water in the electrolytic cell 1 decreases, the overall weight of the electrolytic cell 1 is reduced, and the originally compressed spring 4 pushes up the electro...

Abstract

The invention belongs to the technical field of electrolytic cells, and particularly relates to a PEM electrolytic cell which comprises an electrolytic cell body and a bottom plate, the electrolytic cell body is located over the bottom plate, a PEM film with the uniform thickness is arranged in the electrolytic cell body in a cushioned mode, and the lower side wall of the electrolytic cell body and the upper side wall of the bottom plate are fixedly connected through multiple sets of evenly-distributed telescopic columns. A corresponding spring is arranged on each telescopic column in a sleeving mode, the two ends of each spring are fixedly connected with the lower side wall of the electrolytic cell and the upper side wall of the bottom plate correspondingly, a water supplementing device matched with the electrolytic cell is fixedly arranged above the bottom plate and comprises a water storage tank and a water supplementing hose, the water storage tank is fixedly arranged above the bottom plate, and the water supplementing hose is fixedly connected with the water storage tank. The water replenishing hose is communicated with the water storage tank and is inwards inserted into the electrolytic bath; pure water is automatically and timely supplemented into the electrolytic cell by utilizing the change of the overall weight before and after the reaction in the electrolytic cell, manual control is not needed, and normal hydrogen production of the pure water in the electrolytic cell is guaranteed.

Description

technical field [0001] The invention relates to the technical field of electrolytic cells, in particular to a PEM electrolytic cell. Background technique [0002] The electrolytic cell is composed of a cell body, an anode and a cathode. Most of the anode and cathode chambers are separated by a diaphragm. According to the different electrolytes, they are divided into three types: aqueous electrolytic cells, molten salt electrolytic cells and non-aqueous electrolytic cells. In the cell, oxidation reaction occurs at the interface between anode and solution, and reduction reaction occurs at the interface between cathode and solution to produce the desired product. At present, the plates of relatively mature PEM electrolytic cells at home and abroad generally use metal (titanium) materials. Processed, in electrolysis technology, PEM electrolyzer plays an essential and important role as an important equipment for pure water electrolysis hydrogen production. [0003] In the existi...
