For about a couple of years now I been in the HHO circle. This is research and development of producing Hydrogen from water. Common practices in this field use electrolysis and steam reforming methods. A major goal in this field is to have production on demand. In other words enough to run a 100% on hydrogen gas as it is produced. Thus no storage is needed. A recent breakthrough was discovered using a Molybenum sulfide film as a catalyst. You can read it here http://www.eurekalert.org/pub_releases/2011-04/epfd-acd041211.php . It has a stepping effect. Thus the longer the electrolysis is ran, tempurature rises and more hydrogen is produced. This is just one careristic they mentioned. It also has another effect. A molybenum negative charged electrode doesn't produce oxygen, but instead a electro chemical reaction happens and instead of oxygen bubbles a black residue forms around the electrode.

I conducted experiments since Wednesday using Molydenum rods, 99.6 pure. The alloy is kind of expensive, at least for my budget, but with the right financing either the alloy based cell or a polymer based cell can be manufactured. In either case this can possibly replace gasoline. If not it will definately increase your MPG a lot better than current HHO cells. SInce oxygen isnt produced this will have no effect on ECU sensors. I am looking for financers, partners in this where we can change the world. edit
