AI Technical Summary
In existing water electrolysis hydrogen production equipment, the way the electrode assembly is fixed leads to poor gas-liquid transmission, unstable electrolysis efficiency, and potential safety hazards. Furthermore, the unstable distance between the electrode and the diaphragm affects the voltage fluctuation of the electrolyzer.
The device employs a symmetrical structure with cathode assemblies on both sides of the bipolar plate. The cathode assemblies are detachably connected to the bipolar plate. It is equipped with isolation gaskets and cathode gaskets. Combined with the detachable electrode frame and diaphragm design, the stability and sealing of the electrode assembly are ensured.
It improves electrolysis efficiency and stability, reduces operating costs, enhances safety and sealing performance, extends the service life of electrodes and bipolar plates, and optimizes current distribution and gas discharge paths.
