According to Honda, the new fuel-cell stack is 20% smaller, 30% lighter and has a higher output of 100 kW (136 PS; 134 bhp) . The new powerplant is 180 kg lighter, 40% smaller in volume and has a high energy efficiency of 60%, compared with 20% for most internal combustion engines, 30% for most hybrid powerplants and 50% for the previous generation FCX.

The new V Flow FC Stack features a revolutionary cell structure in which hydrogen and air flow vertically rather than horizontally. Producing a high-energy output of 100kW, the new fuel cell stack is dramatically lighter and more compact that its predecessor, with a 50% improvement in output density by volume, and a 67% increase in output density by mass. Moreover, the fuel cell system is 65% more compact, with a one-box construction replacing the two-box construction. Rather than under the floor, the fuel cell stack is positioned in the central tunnel, allowing for a low floor and low overall height.

To develop a fuel cell vehicle worthy of the Honda name, our engineers worked tirelessly to ensure that the FCX Clarity was:

• Safe for the public
• Operable in freezing weather
• Able to drive a reasonable range before refueling
• Easy to refuel
• Sporty and fun to drive
• Spacious and comfortable

Each generation of the FCX Clarity has brought Honda closer to achieving these goals, and we are proud to introduce the FCX Clarity to the world.

Since the first Honda fuel cell vehicle was unveiled in 1999, dramatic changes have taken place in rapid succession. The fuel cell stack in the 1999 vehicle was very large and bulky. By developing and working to perfect our own Honda Fuel Cell (FC) stacks, Honda has made them significantly smaller and lighter. As a result, the design of the vehicle itself has also gone from tall and boxy to sleek and elegant with a roomy and comfortable cabin.

Honda has brought the fuel cell vehicle from the lab to the fleet and finally to the public. The major barrier now is building up the hydrogen supply infrastructure. We have a strong interest in this area as well and we are hard at work perfecting a Home Energy Station that may supply power to the home in addition to the family car. With these developments, Honda is paving the way for a clean and efficient hydrogen-based society of the future.
