The emissions of a fuel cell are mostly (all?) heat and water, so they
can be used indoors- especially for "short" periods of time, as in a power
emergency. (probably not a good idea to fill the unventilated server room
with hot, moist air- but in an emergency it could be done) At least you're
not going to poison yourself, or those nearby- a big plus in my book.
Some areas will prohibit you from storing liquid fuel on premisis.
Storing a couple 20lb H2 tanks (or CNG/LPG/propane if the cell can do a
clean conversion for you) is much more acceptable (if no less dangerous
under proper conditions) than a having a big jug of diesel around.
In cramped quarters, the noise of a generator could get annoying really
fast- and remote location can present problems of its own.
Like I said, there are lots of companies promising to deliver products
that look suitable, and some that supposedly already have. (but we all
know how firm tech-related release dates are/not) I was hoping (but not
really expecting) to hear from users with deeper pockets about what I
think is a killer technology for this type of application.

P.S. I'm building a bookmark list of things people send, and will post
here if and when it seems worthwhile. Nothing dramatic yet, but a few
mildly interesting things.
