I am looking for some info I just heard that someone in Victoria BC Canada
invented a fuel cell that will work with salt water and titanium plates has
anyone heard of this yet if so let me know this sounds to good to be true I
know but you never know the fuel cell idea could work with something else
besides hydrogen..

I think you are referring to this:

http://www.greenvolt.com/index_2.html

PM-122T dry weight is approximately 5.3 lbs/2.4 kg . This unit is capable
of delivering 3,500 Watt-hours of electrical energy (per set of anodes and 2
liters of saltwater). Thus the Specific Energy is 1,458 Wh/kg or 121 Ah/kg.
This performance is 4.5 x better than any Lead/Acid Battery, and is
delivered by the PM-122 at a dry weight of about 1/10th of a Lead/Acid
Battery. The PM-122 can be easily carried to any location. The electrolyte
needed to activate the unit is only added when and where the power is to be
generated. The additional weight of the typical "pickling salt" (NaCl)
additive (later added, if sweet water is used), is only about 60 gm or 1/7th
of a pound to make 2 liters of electrolyte, of which half is in the unit and
half is in the reservoir (when a reservoir is used).

Only $8+ per kilowatt-hour! Yowza! [Doesn't appear to be
rechargable...]

Also not clear if it's 35 hours of on-time, or if you get the
{3.5,11.9} KWHRs before the {electrolyte,anodes} are exhausted...

Nice emergency battery for marine applications, though. Of course,
$200 or $800 worth of lithium batteries will probably get you a lot
further...

a qote from the site http://www.greenvolt.com/index_2.html

Alkaline fuel cells (AFC's) that use potassium or sodium hydroxide-in-water
solution as the electrolyte and operate between -40 ºC to 60 ºC.

for as far as i know water is frozen at 0 and maybe somewhat lower with
sodium hydroxide in it how could this work??
