Abstract
Electric field polarization is used to increase the storage volume of the stored gas. Increasing the pressure of the loaded gas and simultaneously increasing the polarization voltage, and polarizing the container wall, the pore substances and the loaded gas by an electric field; thereby realizing the polarized adsorption of the container wall and the loaded gas; polarized adsorption of the porous substance and the loaded gas; polarized adsorption between the loading gas and the loading gas. The amount of loading gas is greatly increased. The stronger the field intensity of the external electric field is, the stronger the polarization intensity is, the greater the pressure intensity of the external input gas is, and the more the stored gas is. After polarization is removed, the loaded gas is desorbed with the container wall, the loaded gas is desorbed with the pore substances, and meanwhile, the gas is released to reduce the pressure of the loaded gas and release the gas. The electric field polarized gas adsorption system can store hydrogen, oxygen, nitrogen, helium, chlorine, fluorine, neon, argon, xenon, radon, hydrocarbon compound, etc. at normal temperature in high density.
