What is a dry cell hydrogen generator and how
does it differ from a wet cell hydrogen
generator.
The following is courtesy of LightSmith Studio
"Dry Cell" is a common name for a particular design of hydrogen
electrolyzes, or HHO generator. The name sometimes confuses people
because it still uses electrolyte in water like any other electrolyzes.
But it has some properties that make it a better design, and we will
show you how these properties could bring about the name of "dry
cell". Perhaps a better name could have been found for this design,
but it's pretty clear that the name is here to stay. Just for your
reference, the Hydro*Star Generator is considered to be a Wet Cell
Hydrogen Generator. (Click here for the Hydro*Star Generator info.)

With the dry cell design, the whole cell, or the electrodes are not
submerged into an open bath of electrolyte like the Hydro*Star
electrodes are and some other common types of HHO generator are.
Instead, the dry cell's plates are separated by rubber (or similar
material) gaskets, and the electrolyte is confined inside those gaskets.
The edges of the plates, including all of the electrical connections are
outside of the electrolyte bath. Here is an image of one of our cells
that will help illustrate this:














You can see the edges of the plates between the black gaskets. What
is not so clear in this picture is how the electrical connections to the
plates are also outside of the electrolyte bath. But they are. Tabs on
the plates are used to make the electrical connections. These are the
only parts that are dry, and rightly or wrongly, give the dry cell its
name.

In order to get electrolyte in to the cell plates, and to let the gas get
out, the cell plates have holes in them. 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. Similarly, there are holes at the bottom of
each plate to allow the electrolyte to circulate. The following photos
show where the gas and electrolyte are connected to the cell. The
upper fitting allows the HHO to get out of the cell, and the lower
fitting is for replenishing electrolyte.









So to summarize, the points that make a design a "dry cell", are that
the edges of the plates and the electrical connections to the plates are
dry, or are outside of the electrolyte bath. That's basically all there is
to it. (To see the dry cell generators and prices offered on this site,

            Advantages of a Dry Cell

So, what's all the commotion about? Why is this a better design?
There are 2 main reasons:

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

                         Summary

So that's a "Dry Cell". It is a very simple concept. There are still a
great many variations in this design from manufacturer to
manufacturer. Number of plates, how the plates are powered, and how
much voltage is applied from plate to plate, are just some of the
parameters that can vary. But if they are dry cells they have the
qualities described in this article.

We have designed our cells so that they are maximally efficient, yet
are still cost effective. Despite their low cost, we don't scrimp on the
materials. We feel that our dry cells are not just the best cells, but one
of the best values available in the industry today.
