cooler quite a bit (spacecraft applications) in a unit I had in the car. I tried it on the boat but the power draw was WAY higher than my Engel unit I now have and even more than a normal compressor system. I have visited two different fuel cell companies (in person) in hopes of using one. But they always thought of there unit as "THE" power system for the boat. I tried to tell them that they would be part of the system, not the only source. For a time, Defender had a fuel cell system for boats, and I have seen a number of system for sale - now. But the effort of carrying around the hydrogen source (compressed gas or other) was making it to justify on a boat. Not a fuel source you can count on in a remote area.

BUT, I do have ample solar, and a reefer system that uses 35% less energy (demonstrated now at CES, not in the lab) looks good to me.

I first had a standard reefer in my boat that used way more power than I could generate for more than a week trip. I then moved to a unit that was great (at the time) as it only used 4~5 Ah. What an improvement. I then went to our current Engel unit that uses quite a bit less (2.4 or less as it ramps down). Reduce that number more and it's got my attention.

By the way, if ya want fuel-cells, try Amazon.com - http://www.amazon.com/dp/B00CNB3OUW//ref=cm_sw_su_dp?tag=duiwath-20 or http://www.amazon.com/dp/B00F083HQG//ref=cm_sw_su_dp?tag=duiwath-20 And a batch of other sites.
