Mobile hydrolyzed-aluminum hydrogen production device

Abstract

The invention relates to a mobile hydrolyzed-aluminum hydrogen production device, which belongs to the technical field of hydrogen production, aims to be used for transportation means and consists of a recycling-use hydrogen production bucket, a hydrogen supply part and a hot-water supply part, wherein reaction materials used in the invention are water and hydrolyzed aluminum developed by the applicant; the hydrolyzed aluminum reacts in hot water at a temperature of between 60 and 95 DEG C to form hydrogen and alumina; the alumina is reduced into aluminum through electrolysis and then prepared into the hydrolyzed aluminum for recycling use; the hydrogen supply part uses hydrogen-transmitting pipe to combine the hydrogen production bucket, a condensate filter, a hydrogen-storing device, a constant-pressure hydrogen-supplying device and a hydrogen purifier and then supplies hydrogen to a hydrogen-using device; and the hot-water supply part uses a water pipe to supply the remaining hot water of the hydrogen-using device to the hydrogen production bucket through a water pump, an electronic-control tee proportioning valve, an electric heater and the like. The mass ratio of the hydrogen production bucket to the hydrogen yield thereof is about 20 to 1, and is about one quarter of that of a metal hydrogen-storing tank to hydrogen storage capacity. A working medium used in the invention is free from toxicity, harm and smell, safe and convenient to use and cheaper than gasoline. The hydrogen production device has the advantages of simple structure and implementation convenience.

Description

technical field [0001] The invention relates to a mobile hydrogen production device for reacting hydrolyzed aluminum and water, which is especially suitable for vehicles and belongs to the technical field of hydrogen production. Background technique [0002] Hydrogen has the highest efficiency of converting into electric energy through hydrogen fuel cells, which can reach more than 95% in theory, and is basically pollution-free, while the efficiency of internal combustion engines is generally limited by Carnot cycle to 30% to 40%, and pollutes the environment. The main obstacles to the use of hydrogen in vehicles are: first, heavy hydrogen storage tanks, the mass ratio of tanks to hydrogen is about 80:1; second, the poor stability of hydrogen storage metals and high costs; It restricts the application of hydrogen in vehicles. Therefore, people are studying hydrogen production devices and materials for light weight, small volume, safe, economical and convenient vehicles, som...
