Title:
HYBRID HYDROGEN PRODUCTION SYSTEM COUPLED WITH SUPERCAPACITOR, AND CONTROL METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/231274
Kind Code:
A1
Abstract:
The present invention relates to a hybrid hydrogen production system coupled with a supercapacitor, and a control method therefor. The hybrid hydrogen production system comprises an alkaline electrolytic hydrogen production subsystem, a shunting module, a supercapacitor and a power generation subsystem, wherein the power generation subsystem is connected to the shunting module; the supercapacitor and the alkaline electrolytic hydrogen production subsystem are respectively connected to the shunting module; and according to whether there is a current fluctuation that exceeds a preset threshold value, the shunting module inputs a stable current into the alkaline electrolytic hydrogen production subsystem and inputs a fluctuating current into the supercapacitor. Compared with the prior art, the present invention has the advantages of the efficient and stable work of an electrolytic hydrogen production system being able to be guaranteed, the energy utilization rate being able to be increased, etc.
