Anyway.
So we are wanting to use only waste materials in this process. Ok, so we can use gal iron. Simple. what would a seperator like and ionic membrane or a salt bridge do? Not much. Maybe stop the electrodes touching if we want to use the rechargeable method. Ok, so scrap the membrane.
So, if the Sulfuric Acid instantly attacks the gal iron to create our hydrogen, what are we going to use for electrodes? Well, why not use more gal iron? Will it get eaten away by the acid? No. Why?
You see the acid is an electrolyte. It will eventually get saturated with iron and Zinc Ions and the reaction will stop. So in that case we can safely use some gal iron as our electrodes. Then as we apply current to the two electrodes, the iron and zinc will seperate out of the acid and move to each electrode. Basic Electroplating without the real plating effect. Now we also have a large surface area due to the iron and Zinc metal precipitate. Stop the current and the acid then attacks the metal again creating more H2. Or we could ad Ammonia (NH3) and get the same result? Or why don't we do both?
We having fun yet?
Also what interesting properties do Ammonia and Ammonium Nitrate have? Do Endo and Exothermic reaction sound familar? We could have some fun with this.
