Description

The present invention relates to a galvanic gas oxygen-hydrogen cell and consists in the use of platinized nickel oxide monoxide as a catalytic additive in a hydrogen electrode.

An electrochemical generator is, as is well known, a battery of hydrogen-oxygen gas-electroplating cells formed in a single complex, in which a separate gas element is a cell.

The electrodes are rubber-graphite membranes, which also contain the active material of the catalyst. Electrodes made in the form of thin disks work in such a way that they are in contact with an alkaline electrolyte on one side and gas on the other. Due to the gas permeability of the electrodes, the contact necessary for their action is made: gas, electrolyte, electrode active substance.

In the attached drawing of FIG. 1 illustrates the invention, being a constructive embodiment of a gas element, but not a subject of the invention per se.

In FIG. In diagram 1, one can see the arrangement of mono cells in the electrochemical generator. Each mono cell consisting of a positive and negative electrode, with

the electrolyte between them is indicated in the diagram by the letter T. Gas prozora are formed between mono-cells for oxygen O and for hydrogen Hj.

As can be seen from FIG. 2 and 3 of the accompanying drawing, depicting a general view of the structural design of the electrochemical cell, the system of monochacks is inside casing 7. For the distribution of gases and electrolyte between the individual mono cells in the cell, there are in particular sectors formed by dividing the annular space between the casing and the mono cell wall system. Every two diametrically opposite sectors, hydrogen, oxygen or electrolyte flows in and out of individual mono cells. Rubber gaskets 2 were laid around their periphery to distribute the gases and the electrolyte in the cavities between the electrodes (in the right order), and a gap in the cavities to which gas or electrolyte from the sector should flow is left against each given sector. For example, an electrolyte enters the lower sector through the tube 3, from where through the holes formed by rubber gaskets 2 into electrolyte openings, from where it goes out of the element casing to the upper sector and through the tube 4. By the same principle occurs the distribution of gas-hydrogen or oxygen, but through the side sectors.

Oxygen, for example, comes from the lower left sector and exits from the upper right sector, hydrogen comes from the upper and left sector and exits the lower right sector. The collection of current from individual mono cells is carried out using appropriate jumpers and busbars supplying current to terminals 5.

In practice, electrodes can be made by depositing a mass of rubber, graphite, active material, as well as inorganic cementitious additives onto the metal mesh and subsequent pressing after drying.

The basis of the electrochemical cell, as can be seen, is the work of the battery of gas elements in the common electrolyte. The magnitude of the current losses associated with the operation of a battery of cells in the common electrolyte, from the shunting effect of the common electrolyte located in the lower sector, is controlled by the size of the holes communicating the electrolyte sector with electrolytic fluorescence.

The subject matter of the invention.
