Which is better and why- hydrogen fuel cell cars or gas/petrol/diesel cars?

Question

and which do you believe is more efficient and cost effective?

Answer 1

hydrogen fuel cell cars is more better.

because hydrogen gas is more environmental friendly than others.

hydrogen fuel cell will produce water as their waste,

H2+O -->H2O

the mass of the particle gas for hydrogen are less weight than others particle gas

Answer 2

hydrogen fuel cell cars are better since it is not harming our mother earth in the fact that it produces water as waste instead of greenhouse gases.It is a little sacrifice to spend a little more money for fuel than suffering the effecs of global warming in the future.Another fact,it is as efficient as petrolium fueled

vehicles

Answer 3

Neither one.  Remember when General Motors shut down the EV1 electric car, because they said the market won't tolerate the limited range?  Fuel cells are much worse.

Hydrogen is hard to store because it takes a lot of hydrogen to go very far.  Use enormous amounts of energy to compress hydrogen to 10,000 PSI and put it in a large tank that fills the trunk.  And you still can't beat the range of a cheap electric built with golf cart batteries from Sears.  

My money's on batteries.  It's a much more efficient way to carry energy than trying to convert water to hydrogen and back.

The gas/petrol/diesel all have the problem of expensive limited supply.  Biodiesel might end up working out, it's got a very powerful supporter named Boeing for obvious reasons (trains beat airflight when gas is $4-$10 a gal.)

I personally think electric, and plug-in hybrid electric ("Electric with benefits") will be the big winner.
