Abstract

The invention provides a water electrolysis hydrogen production device which comprises a heat exchanger, and the heat exchanger comprises a first inlet, a first outlet and a second inlet; the water tank is used for containing electrolyte and is connected with the first inlet; the electrolytic bath is connected with the first outlet, so that the electrolyte in the water tank sequentially passes through the first inlet, the heat exchanger and the first outlet to enter the electrolytic bath; the rectifier is connected with the electrolytic bath to output direct current to the electrolytic bath, the rectifier comprises a water cooling part used for absorbing heat of the rectifier, and a water outlet of the water cooling part is connected with the second inlet to enable fluid in the water cooling part to enter the heat exchanger through the second inlet, so that the fluid in the water cooling part exchanges heat with electrolyte in the heat exchanger; the device for producing hydrogen by electrolyzing water solves the problem of low energy utilization rate of the device for producing hydrogen by electrolyzing water in the prior art.

Description

technical field [0001] The invention relates to the field of hydrogen production by electrolysis of water, in particular to a hydrogen production device by electrolysis of water. Background technique [0002] As the most potential clean energy, hydrogen energy has the advantages of non-polluting products and high calorific value. At the same time, hydrogen energy can be coordinated and interchanged with wind power and photovoltaics to accommodate renewable energy, which has attracted more and more attention in recent years. [0003] At present, the electrolytic water technology is relatively mature, but the conversion efficiency is low. How to better improve the electrolytic water conversion efficiency, reduce the response time, and improve energy utilization is of great significance. [0004] During the hydrogen production process, the electrolyte needs to be heated to meet the production requirements. The heating methods in the existing hydrogen production equipment incl...
