Description

Technical Field

[0001] This utility model relates to the field of electrolyzer technology, specifically to a CNC alkaline electrolyzer system for hydrogen production combined with biomass molecular electro-oxidation, which is particularly suitable for combining biomass molecular electro-oxidation with alkaline water electrolysis to produce hydrogen, thereby achieving efficient energy conversion and utilization. Background Technology

[0002] Traditional alkaline electrolyzer hydrogen production technology suffers from high energy consumption and limited efficiency, and is typically not coordinated with other resource conversion processes. On the other hand, the treatment of biomass waste (such as straw and fruit shells) mostly employs incineration or fermentation, which has drawbacks such as high carbon emissions and long cycles. In recent years, biomass electrochemical oxidation technology has gradually emerged, which can convert biomass molecules into high-value chemicals through electrocatalysis. However, in existing technologies, hydrogen production through electrolysis and biomass oxidation reactions are mostly independent systems, failing to achieve the synergistic utilization of energy and materials.

[0003] Existing patents propose an alkaline electrolyzer hydrogen production device, but it does not integrate biomass processing functionality; other technologies, while involving biomass electrochemical conversion, are not integrated with a hydrogen production system. Furthermore, existing electrolyzer systems lack automation control, failing to adjust parameters in real-time according to actual operating conditions and energy demands. Therefore, an integrated, numerically controlled combined system is urgently needed to reduce energy consumption and improve resource utilization efficiency. Utility Model Content
