The electrolysis cell to the to prepare of 1996 and of oxygen using one of the gases produced in order to cool the cell and method of preparation of 1996 and of oxygen by means of this system
An electrolysis cell system includes a compact electrolysis cell comprising gas diffusion electrodes on each side of an aqueous electrolyte retaining matrix. A portion of the hydrogen gas produced by the cell has water added thereto and is recirculated through a thermal exchange portion of the cell to remove waste heat from the cell and create a temperature gradient thereacross. The amount of water introduced into the recirculating gas stream is controlled to maintain a predetermined temperature of the gas stream emerging from the thermal exchange portion of the cell. The stream leaves the thermal exchange portion of the cell and reenters the cell in the gas space adjacent one of the electrodes. In a preferred embodiment the water added is sprayed into the recirculating gas stream and the heat laden stream emerging from the thermal exchange portion of the cell passes through a condenser where water vapor in the stream is converted to liquid and where heat is removed from the stream; the water vapor partial pressure of the stream reentering the cell is controlled by keeping the temperature of the stream leaving the condenser within a certain temperature range.
