(Some midnight random thinking)<p>I&#x27;m curious on how easy it is for the hydrogen to diffuse through the water and to the surface where it can be captured.<p>In the picture the electrodes looks like the typical rods suspended vertically at each end of a relatively deep container. For any hydrogen molecule generated at the bottom it would have to travel a long way and possibly be caught by other atoms, molecules on the way to the surface.
Would it be better to have the electrodes close to each other and parallel with the surface. And possibly having the water flow between the electrodes?<p>Basically, can the process be made more or less efficient by altering container shape, placement and area of electrodes and how the water is handled?<p>Oh, and how is the hydrogen then collected efficiently - a minor vacuum to pull it away? What about the exygen?
