Another question we've been hearing, is where to find stainless steel for your HHO Fuel Cell. There are a lot of places to look, all around us. Aside from the obvious choice of a metal manufacturer, machine shop or a welding supply store, even Costco has stainless cookwear.
Our first HHO hydrogen generator was made out of a stainless steel stock pot. We bought it brand new for $9.99 at a nearby department store. You can't cut stainless with an acetylene torch, so other methods had to be found. An angle grinder with a zip disk was used to cut two strips out of the pot. They were pretty thin and hard to work with, but the anode did produce hydrogen right off the first try. Note: there were a lot of razor sharp edges and a couple of cuts, so be careful if you try this! Wear safety glasses and gloves if you use any grinding or cutting equipment.
Since then we have been buying plate in 4 foot by 8 foot sheets. Since this isn't practical for everyone, you can use a variety of kitchen and household items. From platters, to pots, to pitchers, many items are made from 304 stainless.
Speaking of which, some would have you believe that you need to use 316 stainless. We can't figure out why you would need that, unless you will be running acid or hydrogen sulfide through your HHO fuel cell. 316 has extra hardener and anti corrosive elements to it, which also make it harder to bend and cut. So far, none of the 304 we have used has degraded measurably. 304 will conduct a current just as well as 316, and both are non magnetic.
