Multi-stage water electrolysis hydrogen production electrolytic bath and method for adjusting load of multi-stage water electrolysis hydrogen production electrolytic bath

The invention discloses a multi-section type water electrolysis hydrogen production electrolytic bath and a method for adjusting the load of the multi-section type water electrolysis hydrogen production electrolytic bath, and the multi-section type water electrolysis hydrogen production electrolytic bath comprises a left end polar plate (5) and a right end polar plate (9) which are positioned at two ends, and at least one middle anode plate (7) and at least one middle cathode plate (8) which are positioned between the left end polar plate (5) and the right end polar plate (9), and the electrolysis chamber is divided into a plurality of small electrolysis chamber groups (24) by the middle anode plates (7) and the middle cathode plates (8). According to the multi-section type water electrolysis hydrogen production electrolytic cell, grouping control is conducted on the load power and starting and stopping of the electrolysis small chamber sets (24) by controlling the magnitude of current and voltage flowing thr
