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) FY2015 Annual Report.

Subtheme 3:

A dynamic simulation for hydrogen refueling stations (HRSs) has been performed to calculate the temperatures, pressures and flow-rates of hydrogen at an in-vehicle hydrogen container of FCV and at components of the HRSs such as accumulators, valves, and tubes including the precooling systems. The dynamic simulation is very useful to optimize the hydrogen fueling protocol and the specifications of the HRS components depending on the volume of the FCV container. In addition, an accurate temperature measurement system for precooled hydrogen in the transient fueling process has been developed to obtain reliable hydrogen-fueling experimental data required for validating the dynamic simulation.


Subtheme 4:

Transport properties of hydrogen have been measured at low temperatures and high pressures required in the dynamic simulation for HRSs. The accurate properties are essential to ensure the reliability of the simulation results. In this study, thermal conductivities of hydrogen at temperatures of -40 ℃ and 30 ℃ and at pressures up to 20 MP were measured by the transient short hot-wire method. The obtained data are in good agreement with an existing correlation of hydrogen thermal conductivity within 2 % at pressures above atmospheric pressure, and the reliability of the correlation at low temperatures has been evaluated by the present data.
