Hydrogen Cell
The Hydrogen Cell Nav depicts a hydrgen cell prototype with remnant endplates. One still had a sticker.

HHO Prerequisite
Familiarizing with HHO dry cell discoveries and technology is prerequisite in this research. The hho page is long, but details a whole bunch about the discoveries that led to the worlds least expensive and most efficient electrolyzer. The hydrogen cell technology leverages extensively the progress made by team EBN and the dry cell.

Hydrogen Cell
Project time frame: Developing a functional prototype may evolve quickly. However, Unlocking the materials, configurations, and components that allow improved efficiencies may be more time consuming. Fortunately, functionality is of greater importance. The electrical cost of the gases is less significant, to having them. The ability to generate, collect, store, and use (H2) & (O2) is important. (HHO) can not be stored because it is ready to burn, even inside the storage tank! However, (H2) or (O2) can be safely stored. What will develop with a fuel abundance? Once a working cell is prototyped, the focus will shift towards higher efficiency, lower material costs, robustness, etc....

The proposed structure of our proto hydrogen cell: [from left to right] left end plate, gasket, positive (+) electrode plate, (O2) gasket, membrane, (H2) gasket, negative (-) electrode plate, gasket, right end plate.

Electrode Plates
316L stainless steel sheet metal is used for the electrode plates. Standard EBN plates will be used for our prototype during simple membrane qualification. Thus, internal bolting. Electrical connections will be spade terminals (slide on).

What is this mysterious membrane that separates HHO cells from H2 cells? It is simply a porous & non-conductive layer. DuPont's Nafion is available for testing. Many membranes will be tested. A stop at the local bulk fabric supply store, gave several membrane fabrics for testing. I went for silkscreen, but found various ripstop nylons and another unknown weave - might be a polypropylene. Found that the perimeter can be cut to the size of the plates with scissors. Sandwiching the membrane between two plates and clamping is easy. Poking the plate holes with a soldering iron - makes quick holes in the membrane. Which just happen to accurately match the bolt holes in the plates - imagine that! A very anti-climatic solution to what appeared to require expensive diecutting and quantities. You heard it here - no extra charge! [Note: diecutting membranes may be in order, if this ever goes on to production.]

Potassium Hydroxide (KOH) is available and works great. Concentrate the solution more than what is typical for a HHO cell. This is to increase production from the limited surface area of two plates.
