Technical Field

The utility model belongs to the technical field of laboratory paraphernalia, especially, relate to a high-efficient hydrogen generating device.

Background

The hydrogen generator is a hydrogen production device commonly used in laboratories and is commonly used for providing carrier gas for gas chromatographs. The existing hydrogen generator utilizes the principle of water electrolysis to generate hydrogen at a cathode and oxygen at an anode, and then the hydrogen is respectively led into a gas chromatograph and the oxygen is led into a special collecting device.

In the process of hydrogen collection, hydrogen can be doped with oxygen and isotope deuterium in a certain proportion, so that the purity is insufficient, the stability of a gas chromatograph baseline is reduced, and the working efficiency is reduced. The hydrogen generator purifies hydrogen by disposing a palladium membrane in a hydrogen supply pipeline. The palladium membrane can normally work at a limited temperature, if the temperature is difficult to control, hydrogen is contacted with the palladium membrane at low temperature to cause hydrogen embrittlement, or the palladium membrane is oxidized and inactivated at high temperature to cause slow hydrogen feeding speed. The existing hydrogen generator with palladium membrane adjusts the temperature through the heat exchange device, however, the heat exchange device has poor temperature control effect, low purification efficiency and poor working stability.
