Development of New Fuel Cell Vehicle CLARITY FUEL CELL

Article of Honda R&D Technical Review Vol.28 No.1

Summary

The newly developed fuel cell vehicle, the CLARITY FUEL CELL, has evolved to provide new era appeal together with the same usability as a vehicle with an internal combustion engine. The fuel cell powertrain is mounted under the front hood, realizing the world’s first fuel cell vehicle to be commercially available in a five-passenger sedan package. The key technologies in this achievement are the greater compactness and shock-resistant construction of the fuel cell stack, the adoption of an electric turbo air compressor and fuel cell voltage control unit, and the compact drive unit. Optimal placement of the hydrogen tank and increased pressure capacity extend the driving range (reference value) to approximately 750 km, and achieve a hydrogen refueling time of about three minutes. Driving performance is also heightened by pursuing reductions in vehicle body weight and enhancement in its aerodynamic performance, through increased power of the motor, and so on. These efforts have realized a level of usability on a par with vehicles running on internal combustion engines. In further innovation, this model features external power supply functionality, a new linking technology that gives a foretaste of the vehicle of tomorrow.
