fuel cell????
Anyone seen any set ups utilizing a fuel cell to maintain a battery charge in an RV, a couple places I like to go are heavily shaded (in a forest) so solar is not very efficient, want to avoid using a...

They have been around for decades...don't expect them to get cheap and powerful any time soon.
The Watt one celabrated there first instalation in a resident in 2018, which was a huge milestone going from lab theory to an actual instalation. 2014 is when they wone the contract for proof of theory, so hardly decades for this tech. yes fuel cells have been around for quite a while, a canadian company called Ballard has been leading the charge since the lait 80's with there hydrogen fuel cells. but for the RV market it is a fairly young concept, this one using propane to act as the catilist, but to me it isnt efficent enough as it uses 20lbs of propane to produce 87 AH of charge. I guess it would be ok to have as an emergency generator to supliment your solar. the other one is kinda cool using methanol for the catilist source and wont the european inovation award in 2021, but also have there roots around 2017. while I think the second version is ideal for the RV. the 2800pro will put out 80AH of charging a day and can go 43 days runing 24/7 with a outut of 125 watts on two fuel jugs. look like a DEF jug so they would be easy to store and don't have to worry about using your propane. only down side is your around 4-5000 bucks for this model in canada.
