Cheap & Easy Bubbler and Condensator
Due to having engine problems about one year ago using baking soda and then later lye as the electrolyte, I figured many may want to prevent such an occurence with their setup.
My vehicle stalled about 35 miles from home because of my HOD system spewing other stuff than hydrogen into the air intake. The mechanic had to clean the MAF sensor and the throttle body of yellowish brown residue. The throttle body had distinct signs of corrosion that had been taking place as well. Fortunately the vehicle suffered no harm as far as I know.
The above photo shows my modified smack booster idling at about 2 amps (see video clip below) with the output hose going through the cap to the bottom of the bubbler made from a water bottle, from there to a condensator made from another water bottle on the right and from that into a jar of water to illustrate that the hydrogen gas is indeed passing through the bubbler and condensator.
The bubbler is made by drilling two 1/4 inch holes in the cap. The output hose from the cell is pushed down through the hole to the bottom of the bottle, the output hose from the bubbler is pushed in about 1 inch. I did not have to use anything to seal around the holes as the hose sealed itself in the hole. Fill the bottle with tap water to about 3/4 full and you are ready to go with the bubbler.
The condensator is made the same way except both hoses are inserted only about an inch through the cap. The bottle is left empty and if there is any condensate coming through, it will settle as a liquid in the bottom of the bottle...... and can be dumped out as required.
Caution: Do not use these water bottles if you are connected to the Intake Manifold as they will collapse under the vacuum..... use a sturdier material in such cases. No problem when connected to the air intake....
I don't know how long these bottles will last in the environment under the hood, but kept away from any hot spots they should go for quite a while. You can always use some other material to make a bubbler and condensator that will last indefinitely now that you have an idea what is required.
