Toyota has doubled the range of its fuel cell hybrid vehicle (FCHV-adv) mostly by doubling the maximum storage pressure. The maximum storage pressure went from 35 to 70 Mpa, which allows the new fuel cell hybrid to more than double it's range from 205 miles (330 km) to 516 miles (830 km).
They also improved fuel efficiency by 25% through improvements in the fuel cell unit performance, by enhancing the regenerative brake system and by reducing energy consumed by the auxiliary system.
They also improved low temperature starts. Internally produced water was interfering with the Membrane Electrode Assembly (MEA). Toyota engineers have been working to alleviate this issue. Refinements have allowed starts at as low as -30 degrees Celsius.
The FCHV-adv will be available for leasing later this year in Japan. Toyota does not know when it will become available elsewhere.
The fuel cell hybrid mates an electric motor to a fuel cell stack, which means the only emissions are water vapor.
