"Isn't using any hydrocarbon going to give you the issue with pollution that gasoline does" Not really. A fuel cell converts an hydrocarbon to C02. That's it.

"Isn't using any hydrocarbon going to give you the issue with pollution that gasoline does" Not really. A fuel cell converts an hydrocarbon to C02. That's it. A thermal engine like a diesel creates particles like this: http://www.epa.gov/region1/eco/airtox/diesel.html http://www.epa.gov/region1/eco/airtox/diesel.html And the high temperatures creates nitrogen oxides that create acid rain. When you start a car, the catalyst converter needs 5 to 10 minutes to get enough temperature for starting to work.
