Toyota FCHV

[2] The Toyota FCHV and Honda FCX, which began leasing on 2 December 2002, became the world's first government-certified commercial hydrogen fuel cell vehicles.

[3][4][5] Its first commercial fuel cell vehicle was developed from the FCHV-4, which was adapted from the Toyota Highlander body.

[2] The use of the vehicles by government ministries and companies is intended to provide detailed development feedback on the FCHV performance under varied driving conditions.

In August 2009, Toyota USA announced an estimated FCHV-adv range of 690 km (430 mi) from a 6 kg (13 lb) tank of hydrogen, based on a 331.5-mile (533.5 km) test trip in "real-world" conditions between Torrance and San Diego, California.

[8] The FCHV designs are based on the first generation Highlander SUV, although a bus version is also in development.

The powertrain consists of a 90 kW fuel cell supplied from onboard compressed hydrogen tanks, and a nickel–metal hydride battery in parallel.

Battery and fuel cell can provide power to the 90 kW driving motors either singly or together.

The mechanism is very similar to the Hybrid Synergy Drive in the Toyota Prius and Toyota Auris HSD but with the fuel cell replacing the petrol internal combustion engine, thus minimising greenhouse gas emissions at point of use.

[2] For high performance, such as when accelerating from rest, the fuel cell and battery supply power in tandem.

After Expo 2005, some were lent to bus fleet operators, and also demonstrated in fuel cell events.
