The four-seat vehicle rides on an all-new dedicated fuel cell platform. Toyota said today its two high-pressure hydrogen tanks give it a range of 700 kilometers (435 miles).
Kato said the goal is to deliver operating costs, including the cost of hydrogen fuel, on par with the company’s hybrid vehicles. A government environment minister at today's event said the cost of building a hydrogen fueling station should be halved by 2020.
The fuel cell stack is about half the size of the one used in Toyota's previous fuel cell vehicle, a modified Highlander crossover called the Toyota FCHV-adv that was introduced in 2008. It also uses fewer cells and a smaller motor to improve packaging and cut costs.
Tanks storage density is improved by 20 percent over the FCHV-adv. The stack delivers output power over 100 kilowatts, at a power density ratio twice that of the FCHV-adv.
Speaking at the unveiling, Ogiso declined to say what kind of battery the FCV will use. But he said engineers cut costs by using components from Toyota’s hybrid vehicles, including the battery, motor and control unit. That indicates Toyota may stick with its tried-and-true nickel-metal hydride batteries, instead of leaping to lithium ion ones.
