Fuel Cell Super Thread

[rickjhmn]

So one of the questions on here was sanctioning bodies and them not being likely to let less expensive fuel cells get thru tech. Then others talked about building their own fuel cell or modifying existing fuel tanks with a sump. Personally I am fine with whatever, if you want to immolate yourself in a fiery crash have at it but why would personally made cells or home modified tanks pass tech and not a cheaper brand of fuel cell. Surely they must have to go thru some testing etc to be sold and you have something to go on as a tech guy as opposed to one that a guy welded up in his shop. This is also not to say that many guys on here are not awesome fabricators and quite capable to making a cell at least as good as the manufacturers.
