Toyota develops a new hydrogen-powered fuel cell system

The Japanese car maker is working on ways to supply electricity from a fuel cell to a building’s existing wiring.

Power games: Toyota's fuel cell bus power supply system and the V2H.

Toyota Motor Corporation has developed a power supply system that uses electricity produced within a fuel cell (FC) bus to supply electrical power to devices such as home electrical appliances.

The FC bus, which is based on the FCHV-Bus, has two electrical outlets (AC 100 V, 1.5 kW) inside the cabin that can supply a maximum output of 3 kW.

Fuel cell vehicles (FCVs) generate electricity from hydrogen to power a motor. They are environmentally friendly and have more power than electric vehicles.

Toyota is also developing a vehicle-to-home (V2H) system for supplying electricity from an FC bus to a building’s existing electrical wiring, with the goal of providing a maximum output of 9.8 kW for 50 hours.

With a full tank of hydrogen, an FC bus with the V2H system could be used to power the lights inside an average school gymnasium (with a power consumption of approximately 100 kWh) for approximately five days.

Toyota is planning to test this V2H system for FC buses in 2013 and 2014 as part of the Toyota City Low-Carbon Verification Project.
