FCHV-adv is Toyota's latest fuel cell hybrid. It offers a 25% improvement in fuel efficiency and has a single-fill-up cruising range of around 830 km, more than twice the range of its predecessor. It can also operate in -30°C, greatly improving its cold weather performance.

Fuel cell vehicles have the potential to solve environmental and energy problems. Producing electricity through a chemical reaction between hydrogen (stored in the vehicle) and oxygen (from the air),  water vapour is the only emission.

A fuel cell structure comprises electrodes and polyelectrolyte films sandwiched between separators. When hundreds of cells are stacked together, the result is a fuel cell ‘stack’, known as an FC stack.

A fuel cell can convert as much as 83% of hydrogen’s energy into usable power -about twice the efficiency of current generation petrol engines. Toyota began work on FCHVs in 1992. It applies its own HSD® technology to FCHV development, and the Toyota FC stack is a performance leader in fuel cell technology. 

The world’s first production fuel cell vehicle, the Toyota FCHV, was commercialised in 2002. The FCHV-adv, featuring the newly designed, high-performance Toyota FC stack fuel cell and Toyota-developed, 70Mpa high-pressure hydrogen storage tanks, received vehicle-type certification from Japan's Ministry of Land, Infrastructure and Transport in 2008.
