Here's one article that says it's not a problem. As they point out, "the natural evaporation from rivers and lakes, represents 1000 times as much water vapor as would be produced by running the entire transportation fleet on fuel cells". That doesn't include the tremendous evaporation from the oceans.

There's another article in http://www.realclimate.org on this, but it has 125 comments, and I suspect the answer to your question is buried in one of those responses. You need to enter "water vapor from fuel cells" in their search engine.

As for hybrids, they're practical for local delivery people who log around 20000 miles/yr in city traffic. That's where hybrids shine. I get 26 mpg overall with my 4 cyl Corsica, and 37 on the hwy. But I only use 170 gallons of gas/yr, so a hybrid is not for me. A plug-in hybrid, powered by solar panels in my backyard would be a great idea. The little gas engine would come on only on my annual trip to the east coast. Actually, I'd have to make sure it comes on at least once a month, just to keep it from freezing up. The coming Chevy Volt would fit this dream of mine.
