AI Technical Summary
In existing alkaline water electrolyzers, uneven solution temperature leads to reduced reaction efficiency, affecting hydrogen production efficiency.
The system employs a turbulence and heating structure, using a water spray pipe to create a spiral disturbance in the electrolyte. Combined with the arc-shaped anode and cathode mesh design, this ensures uniform heating of the electrolyte and promotes bubble rise, preventing bubbles from remaining and affecting the reaction.
Uniform heating of the electrolyte was achieved, increasing the reaction area and improving the efficiency and rate of hydrogen production.
