bushman10 Posted January 26, 2016 Share Posted January 26, 2016 Recently saw an Australian off road trailer add and it had an Airconditioner in it which, together with the microwave and geyser, was driven by a small Fuel cell and there were no batteries. How does a fuel cell work and why don't we use those in our homes? Sent from my iPad using Tapatalk Quote Link to comment Share on other sites More sharing options...
___ Posted January 26, 2016 Share Posted January 26, 2016 Round trip efficiency of around 40%. So unless you have a good source of hydrogen (byproduct of something else), it's not much good. The only real upside -- if the internet is to be believed -- is better energy density for storage. Quote Link to comment Share on other sites More sharing options...
