Electrolytic cell structure and alkaline electrolyzer

Abstract

This utility model belongs to the field of water electrolysis for hydrogen production technology, and discloses an electrolysis chamber structure and an alkaline electrolyzer. The electrolysis chamber structure includes a main electrode plate, a diaphragm, an annular seal, and an electrode structure assembly. Two main electrode plates sandwich two annular seals, with the inner surfaces of the two main electrode plates and the two annular seals forming the electrolysis chamber. The diaphragm is sandwiched between the two annular seals, thus dividing the electrolysis chamber into an anode reaction chamber and a cathode reaction chamber. The electrode structure assembly is directly placed inside the annular seal of the corresponding reaction chamber. The annular seals circumferentially limit the electrode structure assembly, and the diaphragm and main electrode plates limit it from both sides. This eliminates the need for welding steps on the main electrode plate to fix the electrode structure assembly, effectively improving the structural constraints on the main electrode plate, reducing installation difficulty, saving installation time, and increasing installation efficiency.
