Abstract

The invention discloses a liquid phase pulse discharge hydrogen production device without carbon deposit on surfaces of electrodes and a hydrogen production method thereof. The hydrogen production device comprises a liquid phase reaction chamber, a substrate, a confined space, a first bar electrode, a second bar electrode and a gas guiding hole, wherein the substrate is arranged on the liquid phase reaction chamber in a covering manner, the confined space is used for containing reactants and completing hydrogen production reaction and is formed by the substrate and the liquid phase reaction chamber, the first bar electrode and the second bar electrode are placed in the confined space, arranged oppositely and manufactured by metallic materials, and the gas guiding hole is communicated with the confined space; the first bar electrode and the second bar electrode are partially sheathed in an insulation sleeve, so that front ends of the first bar electrode and the second bar electrode are exposed outside the insulation sleeve; and a collection part is arranged at the bottom of the liquid phase reaction chamber and is used for collecting carbon generated in hydrogen production reaction. The carbon generated in hydrogen production reaction suspends in liquid, does not attach to the surfaces of the electrodes, and has no influence on the discharging current strength and hydrogen production effect.

Description

technical field [0001] The invention relates to a hydrogen production device and a hydrogen production method thereof, in particular to a liquid phase pulse discharge hydrogen production device and a hydrogen production method without carbon deposition on the electrode surface. Background technique [0002] With the development of industry, the consumption of fossil fuels is increasing, and people pay more and more attention to energy issues. At the same time, the society's requirements for environmental quality are also gradually concerned. The sulfide and carbon oxides produced by the combustion of fossil fuels are what people are eager to avoid. , in response to the above two requirements, hydrogen energy has entered people's field of vision. Hydrogen has a wide range of sources, and as a clean fuel, hydrogen has the characteristics of high combustion calorific value, water as a combustion product, and no greenhouse gas emissions to the environment. The hydrogen producti...

Problems solved by technology

Plasma is regarded as the fourth state besides solid, liquid, and gas. Because it contains high-energy active particles, it is widely used in the fields of environmental protection and material synthesis. However, the current method of hydrogen production using plasma is mainly in the gas phase discharge. In terms of hydrogen production technology, the disadvantages of this hydrogen production method are as follows: the gas production flow rate is small, the hydrogen selectivity is average, and the energy efficiency is not high, which limits the development of plasma hydrogen production; during the discharge process, carbon deposits will be deposited on the electrode surface , as the discharge time increases, the discharge intensity gradually becomes weaker, and the hydrogen production effect is greatly reduced
