KIT FOR THICKENING IMPURITIES IN HYDROGEN GAS, METHOD FOR THICKENING IMPURITIES IN HYDROGEN GAS AND METHOD FOR MANAGING QUALITY OF HYDROGEN GAS

摘要

PROBLEM TO BE SOLVED: To thicken impurities in a hydrogen gas by a simpler configuration than before.SOLUTION: A device 10 for thickening impurities in a hydrogen gas comprises a silica film 11 and a container 13. The container 13 encloses the silica film 11. The container 13 is provided with a sample gas introduction inlet 18 and a concentrated gas outlet 20. The sample gas introduction inlet 18 is used to introduce a sample gas into the container 13. The silica film 11 and the inner wall of the container 13 are not closely adhered, and the sample gas introduced from the sample gas introduction inlet 18 is retained between the inside of the container 13 and the outer wall of the silica film 11. The concentrated gas outlet 20 is used to extract a gas between the inside of the container 13 and the outer wall of the silica film 11 to the outside.SELECTED DRAWING: Figure 1
