Does not produce CO2 at time of energy release (clean cities)

1. Hydrogen (as opposed to (L|C)NG / gasoline / other hydrocarbons) wouldn't either.

2. I don't think the where matters for CO2? Sure it's supposed to melt the ice caps and put us all underwater, but I don't think there are any local effects?

The reason California has all these ZEV (zero emission vehicle) regulations is because of smog. It's better to burn stuff at a power plant than on a highway in the middle of LA or the Bay Area. (And you're right, CO2 isn't the issue, it's the other stuff.)

In this respect, batteries and fuel cells are similar.
