Yes, the base is there already. But theoretically, the base infrastructure for hydrogen fueling stations is there as well. Just convert current gas stations. And no, i am not saying this is cheap or an easy process. But neither is building transmission lines, generation etc needed for electric vehicles either.

Using a battery is the same concept, but instead of using electricty to produce hydrogen and then transporting that hydrogen to the car you use that electricty to charge a battery directly in the car without having to physically transport any fuel. You tell me which is more efficient
Electricity has to be produced from something as well. Yes, electricity -> battery -> mechanical is more efficient that the hydrogen process. And yes, battery / electrical powered vehicles are great for the environment. What they aren't good at, is traveling long distances. Hydrogen isn't good at the long distance thing either, yet. But even if you can't drive longer than 300km on a hydrogen fill, you would be able to re-fuel your hydrogen vehicle in a matter of minutes. Instead of waiting for hours it takes to recharge your battery.

You would need the same nuclear power plants for the electrical vehicles as well.

Each technology has it's pros and cons. And again, I could see both having a place in our society in the future. Just for long trips, transport vehicles, buses, etc, I still think hydrogen is the better choice.
