Problems solved by technology
This method is mainly aimed at argon and helium, and dilutes the rare gas by direct contact, which cannot effectively ensure the purity of the export, and the zirconium alloy hydride will gradually lose its purification effect with the amount of hydrogen filtered.
[0006] To sum up, since the prior art still has inconvenience in effectively improving the purity of hydrogen, therefore, in view of the above-mentioned defects of the prior art, the present invention proposes a hydrogen generation system and a method for generating hydrogen, which uses a hydrogen storage The adsorption characteristics of the alloy to hydrogen, to exclude any gas that does not react with the hydrogen storage alloy, and to use appropriate temperature and pressure to speed up the hydrogen purification process

The invention relates to a hydrogen generating system and a method for generating hydrogen, which is used for improving the purity of hydrogen. The hydrogen producing system comprises a supply cavity stored with roughwrought hydrogen, a purification component connected with the supply cavity used for absorbing the hydrogen with high purity in the roughwrought hydrogen, and a heat exchanging component used for carrying out heat exchange with the purification component and adjusting the temperature of the purification component so as to exhaust impure gas in the roughwrought hydrogen, thereby releasing the hydrogen with high purity from the purification component. The invention can acquire hydrogen with high purity and the method adopted by the invention is to generate hydrogen in batch and the hydrogen generated can be stored in the system for a back terminal user to user. The technique needs not to add a plurality of complicated and expensive materials and devices and the generated hydrogen with high purity, which has low cost and is easy to use.
Description
technical field [0001] The present invention relates to a hydrogen generating system and a hydrogen generating method, and more particularly, the present invention relates to a hydrogen generating system and a hydrogen generating method for purifying crude hydrogen using a hydrogen storage alloy to provide higher purity hydrogen. Background technique [0002] The application of hydrogen is the trend of energy development at present. With the increasing development of the industry, the requirements for the purity of hydrogen are also relatively high. For example, impure gases in hydrogen (CO, CO 2 、H 2 O, O 2 and CH 4 ) has a great influence on the performance of fuel cells, and the hydrogen purity requirement in metalorganic chemical vapor deposition (MOCVD) needs to be above 6N, but the current manufacturing cost of high-purity hydrogen is quite expensive (such as palladium membrane, PSA, etc.), making The relative cost of back-end users increases. [0003] Among them,...
