Powertrain System of Honda FCX Clarity Fuel Cell Vehicle
Honda’s unique V Flow FC stack technology is the core of the FCX Clarity’s fuel cell powertrain. A considerable reduction in size and weight and increased power have been achieved, with the powertrain as a whole displaying a weight output density that is 2X higher and volume output density 2.2X higher than that of the previous FCX.
The maximum power of the V Flow FC stack employed in the Clarity has been increased to 100 kW. The new FC stack also achieves a 50% increase in volume output density and 67% increase in weight output density against the previous stack. Low-temperature start performance has also been significantly improved, with the vehicle able to be started at -30 °C.
A new design has increased the maximum power of the drive motor to 100 kW and resulted in the achievement of a smooth, powerful and continuously extendable acceleration feel.
Increased efficiency in the powertrain and superior energy management have enabled the realization of an energy efficiency of 60%, resulting in a level of fuel efficiency 2.1X higher than that of a small gasoline vehicle and 1.4X higher than that of a small hybrid vehicle.
