An example implementation of the invention are explained below with the help of the attached drawing, which schematically shows a device for producing detonating gas.

The device comprises a tank 1 made rotationally symmetric around the middle axis 2 and consisting of a tubular body 3, the which closed upper 4 and lower 5 covers. The entire device is made primarily to be longer than shown.

On the inner wall of the housing 3 is ring-shaped external electrode 6. Inside the housing 3 is ring-shaped internal electrode 7. The housing 3 is filled up to level 8 water 9.

Between the electrodes 6, 7 to a height of 11 has a gel-like ion-exchange substance 10.

The external electrode 6 is connected by a switch 12 plus source 13 current, for example a 12-volt car battery. Minus source 13 current is connected with the internal electrode 7. The polarity may be reversed.

In the illustrated example, the execution level 8 water lies above a height of 11 gel ion-exchange substances 10 and above the open top of the tube internal electrode 7. The electrode 7 may be also closed. Another possibility is that the electrode 7 is from level 8 of the water. Later in the specified exemplary embodiment, the height 11 gel ion-exchange substances 10 lies slightly below the upper end of the outer electrode 6. The device can also be carried out so that this height 11 lying above the upper end of the electrode 6. The internal electrode 7 may be at the bottom of the closed or open. It can be further opened at its lower end or hermetically connected to the bottom cover 5.

When the circuit breaker 12 in the tank 1 happens the electrolytic reaction, at which the positive external electrode 6 are attracted by negatively charged electrons and ions. Positive ions move to the negative internal electrode 7. Thus, in the space 14 between the level 8 of the water and the top cover 4 is formed of detonating gas, and we are talking about natural receiving a detonating gas. This reaction is greatly accelerated by ion-exchange substances 10. Oxyhydrogen gas is a stoichiometric ratio. It can be removed from the space 14 (not shown). This may occur periodically (periodic mode) or continuously. Next is possible by the proper discharge of the tank 1 separate the capture and removal of the resulting hydrogen and oxygen.

Ion-exchange substance 10 is a strongly acidic gel-type ion exchange substance with sulfo-as anchor groups. Ion-exchange substance has the General chemical formula R-SO3-N, where R denotes the matrix, in particular crosslinked polystyrene matrix, SO3- anchor alphagroup, and H is hydrogen.

Mainly ion exchange substance 10 is supported on the move. This is mainly so that the ion-exchange substance 10 is not lowered. The ion exchange material may be maintained in motion by the method of fluidization. When ion exchange is emesto supported in motion, improve gas production and the flow of electrons.

According to another preferred improvement of the ion-exchange substance support in a liquid in suspension. This is mainly due to the fact that the ion-exchange substance or a basic ion-exchange material substances manufactured so that it itself remains in suspension in the liquid, i.e. water 9.

The method can be carried out continuously. For this ion-exchange substance 10 can be continuously fed and drained (not shown). Allocated ion exchange material may be regenerated and re-submitted.

The method may also be multi-stage.

The resulting gas can otkazyvatsa of the space 14. For this purpose you can create in this space 14 of the vacuum. This can continue to accomplish what is passing up gas capture ion-exchange substance 10 and thus will cause the mixing and distribution of the ion-exchange substance 10.

Pressure and temperature can be set so that the method was carried out with optimum efficiency.
