In the beginning of next year, Toyota will start selling buses that run on hydrogen fuel-cells. Toyota FC Bus, quite possibly the largest fuel-cell vehicle available, will be sold in Japan.
After a long time of testing the prototypes in real-life conditions, Tokyo will - at first - see only two fuel cell buses included in the city's public traffic scheme. However, by 2020, when Tokyo is hosting the 2020 Summer Olympic and Paralympic Games, they expect to sell more than 100 such buses.
Developing the CO2-free fuel-cell buses, Toyota has worked closely with its Hino bus and truck division, implementing their know-how. FC Bus can transport around a total of up to 77 passengers (including seated, standing, and driver) and comes equipped with Toyota Fuel Cell System (TFCS), which was originally developed for the Mirai fuel cell vehicle (FCV). Two TFCS units deliver power output of 114 kW each and provide juice for two electric motors with maximum output of 113 kW each and maximum torque if 335 Nm. Ten high pressure tanks hold 600 liters of highly compressed H2.
In the event of an emergency, the fuel cell bus can also serve as a high-capacity external power supply system, providing maximum output of 9 kW and power supply amount of 234 kwh.
