英文要約Title: Research and Development of Technology for Hydrogen Utilization./ Research and Development for Optimization of Domestic Regulation, International Harmonization and International Standardization for FCV and Hydrogen Infrastructure./ Research and Development of Technical standards Review Regarding Preventive Measures of Overfilling on Hydrogen fueling for FCV. (FY2013-FY2017) FY2016 Annual Report.

Subtheme 3:
A dynamic simulation for calculating the temperature, pressure and flow-rate behaviors of hydrogen at an in-vehicle hydrogen container of FCV and the components of the hydrogen refueling stations (HRS) such as accumulators, valves, and tubes including the precooling systems has been improved by compiling several filling methods of hydrogen. For smaller in-vehicle hydrogen containers of two-wheeled vehicles, the reliability of the dynamic simulation is confirmed through comparisons with experimental data.

Subtheme 4:
Thermal conductivities of hydrogen at temperatures of -40 oC and 30 oC and at pressures up to 20 MP have been measured by the transient short hot-wire method. A platinum short wire placed in the sample vessel is heated by the Joule-heating, and the temperature raise of hydrogen filled in the vessel is measured by the platinum wire. The thermal conductivity of hydrogen is derived from the temperature rise by comparing with the simulation using the unsteady state heat conduction equation. The thermal conductivity is estimated to be measured with an uncertainty less than 2 %.
