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.

摘要： Disclosed herein is a halogen cell of which a positive electrode and/or a negative electrode is a gas permeable electrode. 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.

摘要： An electrode device for an electromagnetic fluid flow apparatus, comprising a pair of electrodes which face a pathway of an electrical conductive fluid, and a magnet which faces the pathway and effects a magnetic field in a direction perpendicular to the flow direction of the electrical conductive fluid and to a straight line connecting the two electrodes. Each electrode is made of a hydrophobic carrier with pores of at most 1 .mu.m pore size, the hydrophobic porous carrier having electrical conductivity, gas permeability and liquid impermeability. A gas generated from the electrode may be discharged from the rear surface of the electrode to the outside without releasing from the surface of the electrode into the electrical conductive fluid.

摘要： Disclosed herein is a gas permeable member, in particular a gas permeable electrode, carrying a metal complex on a reaction layer thereof. 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.
