If Fuel Cell Cars only emit H2O?

Question:
Won't that create a safety issue in cold climates causing sheets of ice on all the roads?

Answers:

How does driving with windows rolled down affect my gas mileage?

Water emissions from fuel cells are very moderate, and should not create ice hazards.

What often gets lost in the public discussion of hydrogen is the fact that hydrogen is not a fuel. It is an energy CARRIER, just like a battery. So fuel cell cars are no different from electric cars. And like EVs, you must consider the emissions created during generation of electricity (which are nonetheless lower than comparable gasoline emissions.)
*
Hydrogen is extracted from water, using electricity. Then the fuel cell turns it back into electricity and water. That's a reversible chemical process, exactly what happens inside a battery. All the energy comes from the electricity - the hydrogen 'carries' it.
*
Except that the entire hydrogen process is much less efficient than a battery, especially considering the wasted energy of transporting and storing hydrogen.
*
Also, a fuel cell car will always be more expensive than an electric car, because you are taking an electric car, then adding a fuel cell to it.
*
The only advantage that hydrogen could bring to electric cars is fast fueling. But now that 10-minute fast-charge batteries are on the market, even that advantage is evaporating.

Here's a car (being built right now, in California) that uses the new batteries:

The Phoenix electric pickup truck - using new, advanced Altairnano batteries (based on research from MIT) - can:

Nissan XTerra with 6-speed manual transmission?

-Travel up to 250 miles per charge
-Carry 5 passengers plus cargo at 95mph.
-Charges batteries in as little as TEN MINUTES.
-Has batteries that last 250,000 miles (never need replacement.)

Don't listen to the oil-industry disinfo about powerplant pollution or battery pollution. EVs are much, much cleaner because of their high energy efficiencies.
