Learn everything you need to know about the all-new 2021 TOYOTA MIRAI at the Los Angeles International Auto Show. Join Maggie Clark from "Motor City Maggie" for a walk-around of the 2nd generation of Toyota's innovative zero-emission Hydrogen fuel cell electric vehicle. The only emission is water! Hear all about the new MIRAI including the driving range, design, technology, new interior features, and more! Learn about Hydrogen, how a Hydrogen fuel cell electric vehicle works, and how the refueling infrastructure is growing.
One of the principal aims for the new 2021 Mirai has been to give the car a stronger emotional appeal, making it a car that people will be attracted to by its looks and the way it drives, as well its eco-performance. The new GA-L platform and Toyota’s advances in FCEV technologies have made this possible.
Toyota’s new fuel cell stack and fuel cell power converter (FCPC) have been developed specifically for use with the GA-L platform. The designers have been able to bring all the elements together in the stack frame (including the water pumps, intercooler, air conditioning and air compressors and the hydrogen recirculation pump) with each part made smaller and lighter, while at the same time improving performance. The stack case itself has been made smaller by using Friction Stir Welding, reducing the gap between the fuel cell and casing.
The new Mirai is equipped with lithium-ion high-voltage battery in place of the current model’s nickel-metal hydride unit. Although smaller in size, it is more energy-dense, giving higher output and superior environmental performance. Containing 84 cells, it has a 310.8 rated voltage compared to 244.8, and a 4.0 Ah capacity, versus 6.5 Ah. Overall weight has been reduced from 46.9 to 44.6 kg. The output has improved from 25.5 kW x 10 seconds to 31.5 kW x 10 seconds.
The environmental benefit of driving the Toyota Mirai go beyond zero emissions to “negative emissions” – the car effectively cleans the air as it moves.
A Toyota innovation, a catalyst-type filter is incorporated in the air intake. As air is drawn into the vehicle to supply the fuel cell, an electric charge on the non-woven fabric filter element captures microscopic particles of pollutants, including sulphur dioxide (SO2), nitrous oxides (NOx) and PM 2.5 particulates. The system is effective in removing 90 to 100% of particles between 0 and 2.5 microns in diameter from the air as it passes into the fuel cell system.
