fuel cell

How much Hydrogen is needed to react in a Hydrogen fuel cell?

 

So, my question is if anyone knows or can point me to a link is, how much compressed hydrogen is needed to react with a fuel cell to produce enough electrical power to at least equal the amount of drivable distance as a modern gasoline powered car? I can understand that no one may know this as a result of industry secrets and what not, but ill take anything.

Hydrogen Combustion?

 

What would have to be done for a car to run on hydrogen combustion instead of fossil fuels combustion, not the fuel cell battery and such? Mythbusters did this a while back I think but I was wondering if anyone knew anymore about this idea. What would have to be changed from a typical engine today in order for this to work. Is this idea even possible?

When will someone make a decent EV?

 

I drive only 5-20 miles a day, but part of that is on the highway at 70 mph. I need an electric car that can do decent speed, but I don't have 0,000 for a Tesla.
When are the major manufacturers going to sever this incestuous relationship they have with the oil companies and start selling what folks like me need?
I'll probably always have a fueled vehicle – nitrogen gas or hydrogen or fuel cell or biodiesel or even (gasp) gasoline – for long distance trips and hauling the family.
But for my daily drives to work and back, I don't need capacity, or even much range, just reliability and speed. And I don't seem to be alone – there are a lot of drivers on the road with me who are alone in their cars.
Does anyone have an idea when we might see a real "plug-in" car?

Does no one read the question? "Someday" is no answer, and neither is "no demand" and neither is "try a search." If anyone has an idea, please let me know, but if you haven't a clue, keep your comments, please.
