From jlnlabs eGroup: Chinese patent of method to dissolve water into hydrogen and oxygen without the need for external power supply.
I couldn't find the patent at the EPO (maybe someone can fill in here?), anyway the abstract looks interesting:
Abstract
An apparatus for generating Hydrogen and Oxygen by means of electrolysis
without requiring an external power. There are two main electrodes(the
Anode and the Cathode) built at both sides of the Electrolysis
compartment, in the said compartment there are multiple Electrode plates
and gas separating membranes connected in series. At the upper part of
the compartment, ducts convey Hydrogen and Oxygen separately to the
repsective Gas Concentrating compartments. There is a separation built
between the Electrolysis Compartment and the Gas concentrating
Compartments. The Current Generating Tunnel is at the outskirts of the
Electrolysis Compartment, the electrolyte can flow without hindrance
from these Tunnels to the Electrolysis Compartment. Permanent magnets
are fixed to the wall of the Current Generating Tunnels and Current
Collecting Metal Connectors of both Positive and Negative poles are
fixed to the ends of the permanent magnets for energy collection. These
Metal Connectors are interconnected in series as shown in the drawings,
the first connector is then connected to the Cathode and the last
connector is connected to the Anode of the Electrolysis compartment.
This invention does not require an external energy or traditional power
to maintain the Electrolysis process.

Description of the operation of the apparatus
An apparatus for splitting water into Hydrogen and Oxygen without the
requirement of an external power
This invention concerns a Generator of Hydrogen and Oxygen by means of
electrolysis without requirement of an external supply of energy, such
as electric current, petroleum derivated products or coal.
According to Chinese Patent ZL 95220793, a type of H2-O2 Generator by
electrolysis is disclosed. Such generator has a housing and a liquid
deposit, with anode and cathod on both sides of the housing, with
multiple sets of electrolysis plates and gas separating membranes
inserted in the Electrolysis Compartment. At the top of the compartment
there are two gas concentrating compartments, one for the H2, and the
other for the O2. In order the generator to work, electrolyte has to be
introduced into the compartment, and electricity is required. The
apparatus consumes a great deal of electricity.
The improvement of this invention is the elimination of the external
power source such as electricity, petroleum derivated products or coal
for producing H2 and O2.
This is done by the following solution: an apparatus consisted of a
housing with electrodes at each side of the housing, inside the
Electrolysis Compartment multiple sets of Electrolysis Plates and Gas
Separating Membranes are connected in series, each Plate and Membrane is
framed by isolating elastomer, at the top of the Compartment there are
compartments for the collection of H2 and O2 separately. They are
separated from the Electrolysis Compartment by a division sheet. Holes
are drilled through this sheet in order to convey the gases to the upper
compartments. Outside the Compartment wall, a Current Generating Tunnel
is located, both top and bottom of the tunnel communicate with the top
and bottom of the Electrolysis Compartment. Multiple permanent magnet
bars are fixed to the wall of the Tunnel. Collecting Electodes are fixed
to the north and south ends of the magnet bars for current collection.
The first of the electode is connected to the Anode and the last point
of the last electrode is connected to the Cathode of the Electrolyser.
The apparatus works as follows: Introduce electrolyte into the
Electrolyser Compartment. The electrolyte consists of a Sodium
Hydroxide solution at 20~30% (30% weight NaOH, 70% weight distilled
water), activate the pump to circulate the solution, the circulating
electrolyte within the Current Generating Tunnel will interact with the
Permanet magnet bars, producing positive and negative ions, these ions
cut the magnetic flux and will induce electric currents, the Collecting
Electrodes will collect the induced currents to the Anode and Cathode,
and the Electrolysis will initiate. While the process maintains and
intensifies, heat will be soaked up by the electrolyte and the liquid
will self circulate through the Tunnel by convection, and finally the
circulation will self-sustain, therefore pump can be disconnected
eventually. But in order to archive high production rate of gases, the
pump can maintain its functioning.

Drawing 6 Transversal view of this invention
Drawing 7 Pump location and other particulars
Referencing to Drawing 1 and 2, the apparatus has a rectangular housing
(3), made of alkali resistant plastic (such as Polyethelene or
Silicone), with a removable base (19), On one side of the Electrolysis
Compartment is the Anode(2) and the Electrolytic Plate(12), on the other
side is the Cathode(11) and the Electrolytic Plate (10), Inside the
Electrolysis Compartment (1) there are multiple sets of Electrolytic
Plates (6) with Gas Separating Membrane (4) inserted in-between. Sixty
sets are used in this invention. Each membrane and its respective Plate
are built with its individual isolating elastomer frame (look at drawing
4), The rubber frame (13) is mold formed by injection to the membrane
(4), the membrane is nylon-polyester fabric, of 300 seive finess and
0.08mm thick. The rubber frame (14) is mold formed by injection to the
Electrolytic Plate(6). At the bottom of the frame there is a channel for
pressure balancing(21), also there is a returning path (15) at the
bottom of the basement, through the channels(21), each electrolytc plate
element can balance the level of liquid during the operation. The
Division (8) separates the Electrolysis Compartment from the Gas
Concentrating Compartments, holes (5) are drilled through the Division,
and convey the hydrogen generated at one side of the membrane to one of
the gas collecting compartment (20), the oxygen generated at the other
side of the membrane is conveyed through the another set of holes to
(7). (17) and (18) are exits for the H2 and O2 respectively. Curent
Generating Tunnel(9) are located around the Electrolysis Compartment,
both the top and bottom of the tunnel is connected to the top and bottom
of the compartment. Multiple permanent magnet bars are fixed to the wall
of the Tunnel. For this purpose, 40 Strong Rare Earth Magnets( BaFe) are
used(See drawing 5). Collecting Electrodes (24) and (25) are fixed to
the ends of the magnet bars, according to drawing 6 they are connected
in series and also fixed to the anode and cathode of the apparatus.
Drawing 6 shows the lateral disposition of the Tunnel (22)with respect
to the Electrolysis Compartment, Drawing 7 shows the tunnel is connected
to the compartment through channel (27), a circulation pump (26) is
connected between them. For a higher rate of gas production, the
permanent magents bars can be replaced by electromagnets, but then it
will require an external power source.

(User Info | Send a Message) | | Nothing to get excited about here, the 30% solution of NaOh is the giveaway to how the cell works. Electrolysis of water using DC current from the breakdown of the electrodes by electrolytic action of the NaOH on the plates. The magnets have nothing to do with the process. When reading a patent, keep in mind that its couched in legal terms and the science (or lack of science) is at least secondary. |
