Problems solved by technology

Hydrogen molecules can enter the crystal lattice of many metals, causing "hydrogen embrittlement", which requires the use of special materials (such as Monel alloy) for hydrogen storage tanks and pipelines, and the design is more complicated

Abstract

The invention discloses a method for producing hydrogen from plant acid, which uses citric acid and high-purity iron powder to produce chemical reaction to produce hydrogen: the method of the invention can produce a large amount of hydrogen, and the hydrogen production bottle does not generate heat during the hydrogen production process, and there is almost no temperature change. Safe, reliable, and low cost; the hydrogen production method of the present invention can provide a continuous hydrogen source for the fuel cell power generation module, and only needs to replace the plant acid solution, and does not need to replace the iron powder for a long time, especially suitable for the military market and electronic digital electronic equipment, etc. power supply.

Description

technical field [0001] The invention relates to the field of new energy technology, in particular to a method for producing hydrogen from plant acid. Background technique [0002] Under normal temperature and pressure, hydrogen is an extremely flammable, colorless, transparent, odorless and tasteless gas. Hydrogen is the gas with the lowest density known in the world. The mass of hydrogen is only 1 / 14 of that of air. That is, at 0°C and under one standard atmospheric pressure, the density of hydrogen is 0.0899g / L. Therefore, hydrogen can be used as the filling gas for airships and hydrogen balloons (due to the flammability of hydrogen, the safety is not high, and most airships are now filled with helium). Hydrogen is the substance with the smallest relative molecular mass and is mainly used as a reducing agent. [0003] Hydrogen was first produced artificially in the early 16th century by subjecting metals to strong acids. From 1766 to 1781, Henry Cavendish discovered the...
