(127e) Leakage Hydrogen Gas Can be Removed By a Passive Eliminator to Prevent It Accumulate in a Confine Space. It Can Significantly Reduce the Risk of Explosion.

Safety concerns regarding hydrogen gas have always been a primary focus for those promoting hydrogen energy development. In accidents involving hydrogen, even small leaks in confined spaces can lead to the accumulation of hydrogen gas, resulting in explosions and fires. This scenario is a significant worry for hydrogen users. Historically, safety measures have been limited to detection devices that issue alarms. We have recognized this gap in safety measures and invested substantial research resources into developing a device called DHC, which can automatically eliminate hydrogen gas at room temperature. This device catalytically converts hydrogen into water without the need for electricity. In this research, We introduced 4 LPH of hydrogen gas and allowed it to react with DHC at room temperature, recording the concentration change over time. From the concentration curve, we observed that in the absence of DHC, the hydrogen concentration would increase proportionally over time after introduction. However, when DHC was present, the concentration initially increased and reached a peak of 4400 ppm, after which it stopped rising and began to decrease. Eventually, the concentration stabilized at 2800 ppm. This study developed a technology to remove leaked hydrogen gas from a confined space, which can be applied in environments with increasing use of hydrogen to reduce the risk of hydrogen explosions.
