The word

HFC Black Cab - Intelligent Energy CEO and London Mayor

The Fuel Cell Black Cab uses a fuel cell from Intelligent Energy (with 30kW output) as a range-extended for a plug-in electric system. The batteries are 14kWh lithium-polymer and the motor is a 100kW (peak, 55kW continuous).

The cab can go up to 81mph and has a range of over 250 miles on a full tank of hydrogen. It goes from 0-30mph in 4.5 seconds and 0-60 in 14 seconds. The car carries 3.7kg of compressed hydrogen when fully-fueled.

The cells from Intelligent Energy were designed to feature metallic plate construction for low-cost mass manufacture and high power density. They are also made to have rapid sub-zero start-up to accommodate cold temperature environments.

Lotus Engineering packaged the propulsion system with controllers, batteries, and motor. TRW Conekt led the safety analysis program for braking, steering, and other components and donor vehicles for testing were provided by LTI.

And so ...

While modifications of the original Black Cab chassis were required, the vehicles' bodies appear exactly like their petrol-fueled counterparts.
