- 研究成果概要
- According to the Look-up-Table (L/T) shown in SAEJ2601 in US, high-pressure hydrogen of 70 MPa (H70) can be safely and quickly filled into the tank of a fuel cell vehicle (FCV). But it is necessary to pre-cool from -33 to -40 °C. As a result, operation costs in hydrogen refueling station for FCV, including electricity bills, are expensive.
Last year, I clarified for the first time the difference in hydrogen pre-cooling temperature required for new MC formula filling and L/T filling at a hydrogen station in Japan with the same filling time without sacrificing safety and reported it at the SAE Fuel Cell Interface Task Force Meeting. I revealed the possibility about the mitigation of hydrogen pre-cooling temperature.
This year, I closely recalculated and reported the difference in the hydrogen pre-cooling temperature required for new MC formula filling and L/T filling without the tank volume estimation step, which is the filling previous step.
This research analysis were the basis data for quantitatively incorporating the hydrogen pre-cooling temperature mitigation of the MC formula into the revised SAEJ2601-1 and could contribute greatly.
The revision is expected to greatly help to reduce the operation cost of hydrogen refueling station.
