Device and method for producing hydrogen and generating electricity

Abstract

The invention discloses a device and a method for producing hydrogen and generating electricity. The device comprises an electrochemical tank and an ion exchange membrane arranged inside the electrochemical tank, wherein the electrochemical tank is divided into an anode chamber and a cathode chamber by the ion exchange membrane; an anode and a cathode are arranged in the anode chamber and the cathode chamber respectively, and are connected with a resistance through a wire. The method and the device are characterized in that the anode comprises a catalyzer which can electro-oxidizing corresponding substrates with high efficiency, and an anode base; the cathode is made of a material with lower hydrogen evolution overpotential; the substrates and a neutral or alkaline electrolyte solution are accommodated in the anode chamber, a neutral or acidic electrolyte solution is accommodated in the cathode chamber, and the substrates are catalyzed and oxidized by the catalyzer, and then produce hydrogen under the action of the cathode chamber. The device and the method for producing hydrogen and generating electricity can produce hydrogen in the case that direct current is not provided, and can generate electricity; in addition, the device and the method can be used as a storage technology for hydrogen, and have favorable application prospects.

Description

technical field [0001] The invention belongs to the fields of applied chemistry and new energy, and in particular relates to a device and method capable of simultaneously generating electricity and hydrogen. Background technique [0002] Hydrogen is a pollution-free and renewable energy with high energy density, storage and transportation. With the energy crisis and the increasing demand for clean energy, hydrogen, as a clean energy substance with high calorific value, has attracted people's attention. At present, hydrogen generation technologies mainly include coal gasification, petroleum cracking, biomass conversion, electrolysis of water, solar photolysis of water, microbial fermentation, etc. However, these traditional technologies often produce more pollutants or have higher energy consumption. , conversion efficiency is not high and so on. At the same time, due to the high storage and transportation costs of hydrogen, it also affects its wide application. Therefore,...
