Hydraulic Compressor Safety Test for Hydrogen Stations

다국어 초록 (Multilingual Abstract)

The government has announced its Hydrogen Economy Roadmap to strengthen global competitiveness onthe hydrogen economy by focusing on hydrogen fuel cell electric vehicles and fuel cells. In this regard, theinterest on the economics and safety of the infrastructure of hydrogen stations has also increased. In thisstudy, a test bed similar to an actual hydrogen charging facility was built, and a prototype of a piston-typecompressor was modeled. In this model, the piston was hydraulically compressed to progressively test leakage,leakage rate, and durability and to check for any malfunction. Moreover, the leakage rate, cylinder leakperformance, and compressor operation durability were evaluated for safety; it was confirmed that there wereno abnormalities. Nevertheless, an investigation of the long-term use and operating pressure of the compressoris necessary to verify the safety of developing a100-MPa domestic compressor in the future.
