FCV is a car that runs on the energy generated by the fuel cell. Only water is discharged in addition to electricity.
So it’s attracting attention as a zero-emission vehicle, but there are only a few mass-produced models, including the next Mirai that was tested this time.
It’s lonely compared to EV (electric vehicle), but it can’t be helped considering the overwhelming infrastructure difference between electric power and hydrogen. Furthermore, not only fuel cells, but also most power generation systems, such as hydrogen tanks, have been exclusively re-developed.
Technically, FCV has a higher hurdle. From that point too, the appearance of the predecessor Mirai marked an era.
The control of the FC (power generation) output is done by the flow rate of hydrogen and air supplied per unit time, but of course there is a time lag between the throttle operation and the flow control. Also, when the throttle is off, hydrogen and air build up in the fuel cell.
In the predecessor Mirai, a secondary battery is installed as an auxiliary power supply system, and when the throttle is on, the electric assist and when the throttle is off, charging is done by hydrogen and air accumulated in the fuel cell fuel.
In the next model, the general maturity of FC, such as miniaturization, weight reduction and high efficiency, is progressing, but the basic configuration of said control follows the predecessor.
The major focus of the next Mirai is the change in the concept of mass sales of FCV. That doesn’t mean that adopting FR has improved sportiness.
