Hi Brent,
the water vapor comes from the electrical production (like of), then
then hydrogen combines with the oxygen in the fuel cell, it will from
water (while releasing electrons we can use). This is water vapor
I would like to capture.
Using a water absorption cartridges would work, although this means
planning carrying extra if you plan to operate the fuel cell. Maybe
a simple condenser would work, using waste heat or a little power
from the fuel cell.
Also, another question to ask the Millennium Cell people. How hot
does it run? Can we use that heat (or get rid of it if we don't
want it)?
Cheers,
Ian.

Ian,
Interesting information. From the looks of the date on there PDF file,
they have larger units planned as well. Also there is a note about it
being safe for indoor use with zero harmful emissions claimed. I'm
still not sure if the cartridges take O2 out of the air, but it doesn't
look like you have to provide any from a tank. I'm not sure what your
talking about with regards to water vapor collection. It sounds like
you just pour some water into the unit of which goes into the cartridge
starting a chemical reaction. I wouldn't expect all that much water
vapor to come out of it. But if there was you could have it's vent
going directly into your air circulation system that has water
absorption cartridges inline.
Regards,
