"Requires 1 additional gasket per water compartment"
Assembled Gaskets & Membrane
Hopefully
this information will help advance Dry Cell Technology. A few
experimenters are using Nylon Monofilament Mesh to divide water chambers
into 2 areas; one for hydrogen and one for oxygen. To get an
idea of how this is done, watch the videos below. Notice that they
are using 2 gaskets between each set of plates. The Nylon Mesh is
inserted between the two gaskets (Red line in the picture above). The mesh keeps most
of the Hydrogen on one side, and most of the Oxygen on the other side.
There are special slots in the gaskets for channeling the gases to separate
gas output ports. Instead of HHO coming out of one port, Hydrogen and
Oxygen have their own ports. Watch the videos and you will get a better
idea of how this works.
Membrane Materials being used:
Polyester Monofilament Mesh (works with Sodium Hydroxide, NaOH)
Nylon Monofilament Mesh (works with Potassium Hydroxide, KOH)
Silkscreen Mesh, T165
Uncoated Rip-Stop Nylon
About mesh size: Mesh
size is measured by how many threads of mesh there are crossing per
square inch. For instance, a 165 mesh screen has 165 threads
crossing per square inch. The higher the mesh count, the finer the
threads and holes are in the screen.
A large number of commercial cells put the anode and cathode
comparatively close together, but, in order to obtain reasonably high
purity in the gaseous products, a porous partition was placed between
the electrodes: this, like increasing the distance between the plates,
creates a certain amount of resistance, but it has one advantage of the
latter procedure in that it makes for compactness, which is very
desirable in any plant and particularly so in the case of electrolytic
ones, as one of the greatest objections to their use is the floor space
which they occupy.
The membranes go between the neutral and active plates,
they aid to keep the gases separate with help of the special gaskets.
They are very accurately laser cut for a number of reasons, they have to
fit correctly between the gaskets, and the mating holes need to be
accurate too. The edges must not go past the gasket edges or leaks will
occur, so the membranes are made 2mm smaller than the gaskets (3mm). It
is near impossible to cut these by hand successfully.
The cell
does not claim to separate 100% but the concept looks promising. I think
the hydrogen is going to speed its way to the top...and out. While, the
slow oxygen...which is an accumulating bubble with a membrane...slowly
follows the contours of the mesh divider.
It may be possible to use
this mesh in a bubbler. First, the HHO should pass through the mesh,
which would break up the gases into smaller bubbles. Those bubbles
would rise in a chamber with another layer of mesh. I think the oxygen
gases, which are heavy and slow moving, would linger underneath the
mesh, and the hydrogen would pass through it...since it is moving at 20
feet per second. You would need a barb fitting just under the mesh to
allow the oxygen gas to exit the bubbler. Plus, a fitting farther above
the mesh for the hydrogen. I learned from Joe, of joecells, that the two
gases will not pass through the same hole at the same time. With that in
mind, it may also work with two output hoses at the top of the bubbler.
There are other theories for separation of the gases. One is to use
magnetic fields to help direct the gases out. I know this helps move HHO
up and out of tube cells. Stan Meyer used opposite high voltage
potential fields. Positive repelled the Hydrogen and attracted the
Oxygen.
"Pause" to stop the players from playing at
the same time.
My concept of
the idea:
The membrane is sandwiched between two gaskets.
Hydrogen is collected on one side of the membrane, and oxygen on the
other; the two gases are separated.
You will need two top holes for the gases to exit.
Each hole gets obstructed from the gas producing surface of the opposite plate.
Reverse the gasket, on the opposite side of the membrane.
Keep alternating the gaskets this way.
The drawings below depict the general idea. Gasket shape and design
are left up to you.
Below, is a version using 2 water fills; one for each gas. It would allow
better circulation.
Separation Gasket & Membrane Assembled.
Each consists of 2 gaskets with a membrane sandwiched and glued between them.
These were boiled for 5 minutes after the glue dried. The heat tightens the membrane by shrinking it slightly.
