Hydrogen has attracted attention as an energy carrier, and the development of hydrogen refueling stations is an urgent issue to promote the diffusion of fuel cell vehicles. Accurate thermophysical properties of hydrogen over a wide temperature and pressure range are essential for the design of safe and efficient hydrogen refueling stations. In this study, PVT properties of hydrogen have been measured by a magnetic suspension densimeter with an uncertainty of 0.05 % at 100 MPa. In addition, the vibrating wire method was adopted to measure the viscosities of hydrogen using a semi-circular tungsten wire, and the viscosities from 296 K to 573 K and up to 0.7 MPa were measured.
