The Independent have published a review of the Honda FCX Clarity electric car. 'The FCX Clarity weighs 1,625kg, a typical mass for a large saloon, and the 171 litres of compressed hydrogen in its tank will take it about 285 miles. That is a large, bulky tank, but to liquefy the hydrogen requires much more energy. Coping with hydrogen which is merely compressed is the best trade-off between bulk and efficiency. As for the fuel cell stack itself, this is almost miraculously compact and sits within the Clarity's central tunnel. A decade ago, Honda's experimental stack occupied 134 litres of space, weighed 202kg and produced 60kW. Today's version occupies 57 litres, weighs 67kg and produces 100kW. The final parts of the powertrain, the electric motor, its control unit, and the cooling systems, fit under the bonnet.'
