The newly-developed fuel-cell stack installed to this concept car is 33% smaller than the previous fuel-cell stack and yet realized output of more than 100 kW and output density as high as 3.1 kW/L, improving the overall performance by approximately 60% compared to the previous version of the fuel-cell stack.
Honda's next-generation FCV will be the world's first*2 FCV sedan with the entire powertrain, including the downsized fuel-cell stack, consolidated under the hood of a sedan-type vehicle. This powertrain layout enables a full cabin package that seats five adults comfortably and also will make it possible to evolve this vehicle into multiple models in the future when the more widespread use of FCVs requires enhanced choices for customers.
The Honda FCV CONCEPT is also equipped with a 70 MPa high-pressure hydrogen storage tank that provides a cruising range of more than 700 km*3. The tank can be refilled in approximately three minutes*4, making refueling as quick and easy as today's gasoline vehicles.
Furthermore, the Honda FCV CONCEPT features an external power feeding function*5, which underwent a large number of verification tests with the FCX Clarity. When combined with an external power feeding device, this FCV can function as a small-sized mobile power plant that generates and provides electricity to the community in times of disaster or other events.
Striving to make a contribution to the forthcoming "hydrogen energy society," Honda will continue taking on new challenges in the area of hydrogen technologies including the Smart Hydrogen Station, FCVs and external power feeding devices.
*1 - Honda internal measurement
*2 - Honda internal research
*3 - Honda internal measurement in JC08 mode and use of hydrogen station with charging pressure of 70 MPa The cruising range may be shorter depending on conditions of usage (ambient temperature, traffic, etc.) and how the vehicle is driven (sudden starts, use of airconditioning unit, etc.).
*4 - Time required for refueling will vary depending on conditions.
*5 - Japanese version.
