“…Various studies have been conducted in connection with the development of hydrogen regulators. Mizuno et al [11] have conducted simulation-based numerical analysis studies on the shapes of various slits to reduce the noise of the 35 MPa hydrogen regulator. Choi et al [12] performed transient compressibility flow analysis for the high-pressure regulator to verify that sufficient decompression was achieved, and that the pressure ratio, choking, and discharge flow rate were secured in accordance with the design specifications.…”

Hydrogen emerges as a promising alternative energy source, particularly in fuel cell applications, necessitating efficient and safe charging and storage systems. This paper presents the design and development of a specialized regulator tailored for high-pressure hydrogen environments. Focusing on precision control, the regulator ensures optimal performance and safety during charging and storage phases. In order to improve the unstable response characteristics of the existing commercial hydrogen regulator, which has the same differential pressure generation site and pressure control site, a regulator operating at an ultra-high pressure of 105 MPa was designed by separating the differential pressure site and the control site. And structural safety and performance of the regulator were predicted through structural and flow analysis. The results of structural and flow analysis of a 105 MPa high-pressure regulator that can be used for high-pressure hydrogen charging and storage systems were compared with the experimentally measured values.
