The electrolysis process takes place in an aqueous sodium bicarbonate solution for testing and will eventually use potassium hydroxide in water. For this reason the components of the cell are made of stainless steel with either 304 or 316 grade alloys which should withstand the electrolysis process much longer than any other viable metals.
The power source is a modified computer power supply supplying 12V with a 10A maximum before going to sleep. This particular cell will remain a single cell and will be used in a hydroxy fueled blow torch which i will give to my supplier of stainless steel. He supplies me with his scrap metal at an overly reasonable price. I would estimate that the cell shown here will produce about 700Ml per minute of combustible gas which will be sent out to a bubbler and then passed onto the torch through a flashback arrestor device. The production cell will reside in a PVC pipe and i am hoping i will not have to implement any cooling measures.
If this is the case i will look first look at adding a neutral tube (no direct wire attached) to the cell array. This neutral cell takes on the charge of a nearby cell and shares current with it which should lower the heat a little. In this respect the tube is not really neutral; but using the term is easier for description purposes.
HOWS IT WORK THEN?
When voltage is applied to the electrodes, electrons flow down the negative wire and into the negatively charged cells. From there they find themselves in an electrolytic solution and dance around all excited like on the edges off the metal before attempting to leap across the water bridge onto the positive anode to which they are extremely attracted to. The attraction is so intense that as the electron leaps across the water bridge it collides with the atoms of hydrogen and oxygen (H20) in the water and cracks them in half leaving Hydrogen, Hydrogen and Oxygen.
The liberated oxygen atoms are negatively charged and so are attracted the positive electrode and the hydrogen having a positive charge is conversely attracted to the negative electrode. When enough hydrogen atoms form next to each other they create a bubble and float up to the top of the water to pop. The larger bubbles are created by oxygen going through the same process on the positive side.
The resulting gas is a mixture of oxygen and hydrogen and water vapour which is then pass down a tube and into water (or alcohol) where further oxygen will be lost from the mixture leaving a more concentrated hydrogen gas mixture and a safety device should any of the hydrogen gas ignite and flash back into the tube. Hydrogen has an expansion rate of 1:848 which would equate to one mother of an explosion should the reactor itself combust. The bubbler device just creates a 'first point' of explosion so that the larger main production unit is decoyed. I have seen these bubblers do their job many times. Very loud ... and everything gets wet.
