The gas permeable electrode preferably comprises a hydrophilic layer and a gas permeable layer. Since, in this halogen cell, the decrease of the electrode surface area can be prevented, and the desired gas can be rapidly supplied to the electrode, the quantity of charge is increased and the charging time is reduced.Also disclosed herein is a halogen cell of which a positive electrode and/or negative electrode comprises finely divided hydrophilic portions and hydrophobic portions. In this halogen cell, the quantity of charge and the charging time are also improved.

A central metal of the complex may be selected from lead, chromium, iron, cobalt, nickel, copper, zinc, platinum, palladium, manganese, tin, vanadium or the like. The selectivity of a reaction employing the gas permeable member depends on the central metal so that the gas permeable member can be employed in a wide range of applications including electrolytic reduction of carbon dioxide by suitably selecting the central metal of the complex.The complex, for instance a Pc-complex, may be deposited from sulfuric acid by diluting the sulfuric acid by water to be uniformly dispersed in the reaction layer.

摘要： Disclosed herein are processes for preparing a raw material dispersion and raw material powders for producing reaction layers of a gas permeable electrode. The raw materials are prepared in one aspect of the invention by mixing fine particles containing a surface-active agent, freezing the mixture to a temperature the surface-active agent loses at least part of its function and then thawing out the same. The resulting material exhibits superior catalytic performance because the particles are dispersed uniformly by lack of the function of surfaceactive agent at the time of freezing.The raw materials are prepared in another aspect of the invention by mixing hydrophilic minute particles coated with ion exchange resin, PTFE and hydrophobic fine powders. The resulting material exhibits superior catalytic performance because catalysts contained in the hydrophilic minute particles are neither liberated nor made to flow so that the initial catalytic activities are substantially maintained even after a relatively long period of use.
