Engineers also focused on improving fuel efficiency and this results in a 20% increase in “cruising range.” While the current Mirai can travel 402 miles (647 km) between stops, hydrogen prices in California skyrocketed to record highs last year. This means any increase in fuel efficiency would be a welcome development.

Toyota has developed a new fuel cell system, its third-generation fuel cell system, with 20 percent fuel efficiency improvement.

According to Toyota, the 3rd Gen FC System can be installed in a variety of commercial vehicles, passenger cars, and general-purpose applications, such as stationary generators, rail, and ships.

Japanese carmaker Toyota will unveil the third-generation fuel cell system, plans to roll it out globally after 2026.
