Problems solved by technology

[0004] Commonly used hydrogen production instruments based on palladium membrane purification have multi-valve control. Due to the protection mechanism of the palladium membrane, a set of palladium membrane purification modules usually requires at least five control valves, which not only makes the control complicated, but also increases the space required for the equipment. Volume and weight hinder the advantages of palladium membrane purification in portable applications

Abstract

The invention relates to a high-purity hydrogen generator. The high-purity hydrogen generator comprises a hydrogen production module, a palladium membrane purification module, a vacuum pump, a six-way valve and a three-way valve. According to the hydrogen generator, the system is automatically controlled through the temperature control component of the palladium membrane purification module, the hydrogen generator has the advantages of being simple in device structure, convenient to carry and the like, additional control software does not need to be written, and meanwhile automatic one-button starting is achieved.

Description

technical field [0001] The invention belongs to the field of hydrogen preparation and relates to a high-purity hydrogen generator. Background technique [0002] Common hydrogen production methods include coal to hydrogen, alcohol reforming to hydrogen, alkane reforming, and water electrolysis to produce hydrogen. Among them, alcohol reforming and water electrolysis reforming hydrogen production are widely used in the field of distributed small-scale hydrogen production, especially water electrolysis hydrogen production, which has the advantages of high hydrogen production efficiency, simple equipment, and relatively high purity of the prepared hydrogen. . However, for the vast majority of hydrogen applications, even the purity of hydrogen produced by electrolysis of water cannot be satisfied. Therefore, the purification of hydrogen production is particularly critical in the field of distributed applications. [0003] The purification methods of hydrogen include pressure sw...
