The irony here is that FCVs _are_ electric vehicles. I'm not sure why they think that a fuel cell is so much better than a battery, but hey. I'm interested to see real-world well-to-wheel comparisons of the H2 that is in the fuel stations and local electricity.
They think it's much better than a battery because that's what every Tom, Dick and Harry on the street says when you bring up electric cars - "but I need to tow my boat 800 miles per week! electric is doomed for everyone!"
You can refuel a hydrogen car very quickly - at a similar rate to a gasoline car, and the general idea is well ingrained (plug a pump nozzle into a filling point, dispense fuel per unit volume/mass then pay for it).
With current technology you can overcome one of the primary problems, the low energy density of H2, by using a large pressure vessel that weighs about 100 kg (220 pounds) to store enough hydrogen to give you an equivalent range to a gasoline engine. In exchange for that weight, you're losing some of the heavier components of the ICE drivetrain like the gearbox, and the engine itself can also be lighter (although current fuel cells have been designed to fit into a similar footprint to gasoline engines).
Production is obviously difficult - the current bulk H2 production is steam reforming of methane, which is obviously a fossil fuel dependent process (although perhaps biomass could be used instead, but that's a long way off viable scale), or bulk electrolysis of aqueous potassium hydroxide which is heavily dependent on electricity costs.
There are a few things in the works to improve all of these areas, but it's not as doomed as people make out. Catalytic water splitting is something we are working on, but there are major challenges to it (namely that replicating enzymes from scratch is hard work) that has the potential to make localised H2 production as easy as letting sunlight fall on your tank of water (metaphorically).
The other benefit of H2 fuel cells over pure electric is that you can more easily scale them to bigger vehicles like busses and trucks. As you scale up the energy storage device of H2 vs EV (the H2 tank or the battery), the mass of the battery scales with the size pretty linearly whereas the hydrogen pressure vessel doesn't - you get more volume per unit mass of tank as you make it bigger, making it more efficient for very large vehicles.
This is basically a long-winded way of saying that there are benefits to both technologies and that it shouldn't be either/or - they should complement each other in the same way that gasoline and diesel power trains do.
