    Why it matters

    Toyota is ready to launch the world’s first mass-produced fuel-cell car, posing a threat to German rivals Mercedes, BMW and Volkswagen when it comes to non-combustion powered cars.

  • Facts


    • Engines powered by hydrogen fuel cells emit no polluting gases, but can only be considered to have a zero-footprint if the hydrogen is produced from renewable sources.
    • Platinum, one of the world’s most expensive metals, is the catalyst in these fuel cells.
    • One of the hurdles for would-be manufacturers of hydrogen fuel-cell cars is the lack of fueling stations.

Katsuhiko Hirose’s cheerful eyes are sparkling. The 59-year-old is Toyota’s chief fuel-cell developer. He is now being asked why the world’s largest automobile maker does not have a single electric vehicle with a battery in its lineup.

This is why, when it comes to non-polluting engines, Toyota decided to focus on the Mirai (the Japanese word for “future”), a four-seat sedan with a fuel cell under its hood. It uses hydrogen and oxygen to generate electricity to run its electric engine, and nothing but heat and water vapor come out of the exhaust.
