Or you could just burn gasoline in a 2000W Honda which costs about
$1000, makes almost no noise, is quite light, and will generate less CO2
than the fuel cell system will when you get down to reality since the
fuel cell system is actually powered by the fairly inefficient
electrical grid. And it will cost a ton less as well as delivering 20
times the peak power with commonly available fuel.

BTW, the 1000W EU1000i model will deliver 1000W at 3.8 gallons per day,
and 250W at 1.7 gallons per day. The unit is listed at 790 USD. There
are simple modifications to use a boat gas tank (usually about 6
gallons) with this unit which would make the run time 3 days for most
emergency amateur use before refill. I would take this as a first
responder system in a heartbeat.

I also wonder where one would get the energy to refill the hydrogen for
the fuel cell unit when in a place like New Orleans after Katrina.
Gasoline would still need to be hauled in, and would probably be more
efficiently used providing power directly from a smart generator than
splitting water to make hydrogen which would then be used in a fuel cell.
