Dry Cell

” HHO Dry Cell” is a name that has been attached to a particular design of hho electrolyzers, or HHO generators. The term dry-cell is a bit confusing to some people because they wonder how you can be using electrolysis of water to make HHO gas
if the unit runs dry. Truth is these hho drycells use electrolyte in water like any other hho electrolyzer. However the properties and the design of the hho Dry Cell make it a much more efficient hho generator. Maybe a better name could have been found for this hho generator design, but “HHO Dry Cell” is here to stay.

With most other common types of HHO generators the whole cell is submerged into an open bath of electrolyte and water.
This is not the case with the dry cell design,instead, the dry cell’s plates are separated by rubber gaskets, and the electrolyte is confined inside those gaskets where the main body of the plates is bathed in the solution and no energy is lost.
The edges of the plates, including all of the electrical connections are outside of the electrolyte bath. Designers of “open bath” units such as the Bob Boyce 101 have been experimenting with all kinds of ways to seal the edges of their plates as this is where most of the energy is lost.

The cell plates have holes in them in order to get electrolyte in to the cell plates, and to let the gas get out. This is one area of experimentation with the HHO dry cell that is still on going, hho dry-cell builders seem to have differing opinions as to the number of holes and the displacement of the holes for optimum performance. There are holes at the top of each plate, so that the HHO gas can pass from between the plates to the outer sides of the cell.
The upper fitting on the hho dry cell allows the HHO gas to get out of the cell. There are also holes at the bottom of each plate to allow the water/catalyst to circulate between all plates. The lower fitting on the HHO dry cell is for replenishing the water mixture which is held in a tank separate from the cell.

So to summarize, what makes a hho generator a “dry cell” ?.

Well basically the electrical connections to the plates are dry and the edges of the plates, are outside of the electrolyte bath. This is why compared to a “wet cell” hho generator, where a great deal of electrical current is lost in the water solution and wasted. The hho dry cell is much more efficient.

Why is it that a hho dry cell design produces more hho gas?
Because it is much more efficient, there is not a lot of wasted spaced and electrolyte solution that is not being used and charged with current. The very small volume of electrolyte solution that enters the hho dry cell is subjected to electrical current and able to react and create hho, then exit the hho dry cell generator and recirculate, carrying the hho gas with it to be separated at the top of the reservoir tank.

Advantages Of A Dry Cell

When the edges of the plates are submerged in the electrolyte a great deal of the electrical current passes from the edges of the plates. This current is largely wasted in terms of HHO production. When the edges are outside of the bath, all of the current is forced to travel from the faces of the plates. Therefore all of the current used is utilized in efficiently making HHO gas. This is the main reason the dry cell design has caught on so thoroughly.
When the electrical connections are submerged in the electrolyte bath, the electrolyte attacks them and will eventually destroy them. The plates of our dry cells (and any other reputable manufacturer’s cells), are made of 316L stainless steel. This has been found to have the best properties of resistance to attack from the electrolyte while still giving adequate electrical conductance. However, mounting hardware and wire and cable are very difficult to find in this material, and they are cost prohibitive to use. Therefore copper cable is usually used and a lower grade stainless steel nuts and bolts, and when these are submerged in the electrolyte, they rapidly get eaten away. With the dry cell design, all of these connections are outside of the electrolyte so this isn’t an issue
