Honda has become the world's first car maker to build a production car with a hydrogen fuel cell for power.

The FCX Clarity has zero emissions, as its hydrogen fuel cell power uses the gas to produce electricity to power its motor.

When the hydrogen is combined with oxygen to create electricity, the only emissions are water vapour.

Honda is building 200 FCX Clarity models to begin with, which will be delivered to customers in Japan and California, USA, where there are hydrogen gas filling stations.

The car has a range of 435 kilometres and will cost around $600 per month for the first customers to lease over a three-year period.

These first cars are part of a trial being conducted by Honda ahead of larger scale production for hydrogen-fuelled cars.
