Honda FCX Clarity - Click above for high-res gallery
When we first had the opportunity to drive the Honda FCX Clarity way back in November 2007 we only had about a couple of hours with the fuel cell sedan. John O'Dell, a senior editor at Edmunds, actually got to spend a few days with the Clarity recently when Honda decided to put one in its California press fleet. Like other well-developed, electrically-driven cars, be they battery or fuel cell powered, the Clarity behaves pretty much how you would expect any modern car to drive. The efficient packaging job that Honda has done with the the Clarity means that it has about a quarter more interior volume than a similarly-sized Accord. As drivers participating in GM's Project Driveway and lessees of the Clarity will agree, the technology works. It's just a matter of optimizing and mass producing it to get the cost down.
The real problem lies in constructing a fueling network. With only two stations near his home and office, O'Dell was well aware of the issues. The actual act of fueling was not radically different from putting gas or diesel in a current ICE car. The main difference is that the filler nozzle has a clamp to lock it onto the fuel nipple on the car. Filling takes about 3-4 minutes. After that you're off and running again.
