There are several fuel cell companies out there. I am not sure of their names. If you look in any HP boating magazines there are ads galore for them. Or, you can simply wait 10 seconds and someone here will give the answer I am sure. One thing to be careful of. When installing and using the expanding foam. Be EXTREMELY careful, as that foam expands a TREMENDOUS amount and can crush the new fuel cell. Good luck. I am sure you will be back up in a jiffy.
