Hydrogen vs. Battery Electric Cars

I have been working for a fuel cell company for several years now. The technology is still working out some bugs, as is electric battery technology. One thing I did not see covered in this video is fuel cells as range extenders. In some vehicles, it makes sense to use the fuel cell like a built in battery charger. You get the best of both worlds in this situation. You can cut down on the weight by reducing the number of batteries in the vehicle and still get the benefit of range because the fuel cell is charging the batteries on the fly without the need to stop at a recharging station for extended periods of time.
