摘要： PROBLEM TO BE SOLVED: To prepare the reaction layer of the gas diffusion electrode with a simple preparation process and a reduced preparation time, which has high reducing ability against gaseous oxygen. SOLUTION: The raw material for the gas diffusion electrode is prepared by adding primary fine particles of constituting material for the reaction layer of the gas diffusion electrode, which particles have an average diameter lower than 1 μm, and a surfactant into water under stirring or sonicating condition in order to disperse the added particles in highly dispersed state, and then, after adding fine particles of a fluororesin and dispersing the particles by continuously stirring or sonicating to mix, adding a micelle-breaking agent so as to control the aggregation state of the micelle structure caused by the surfactant dispersing stably the fine particles, and to cause the self-organization of the fine particles of constituting material for the reaction layer with the fine particles of the fluororesin. The objective reaction layer is prepared by using the raw material thus obtained.

摘要： PROBLEM TO BE SOLVED: To provide a gas diffusion electrode which is compact in structure, is capable of uniformly supplying gas to a gas diffusion layer from a gas chamber, is capable of extremely reducing the resistance of power supply to a gas diffusion electrode, may be easily produced, is formable to a large size and is excellent in current collecting efficiency. SOLUTION: A reaction layer 3 is formed on one surface of a conductive porous body 2 in such a manner that at least part thereof exists within this conductive porous body. The part on the other surface side of the conductive porous body has no reaction layer and forms at least part of the gas chamber in an exposed state. A gas supplying layer is formed in a laminar form in part of the inside of the conductive porous body and the reaction layer is laminated on one surface side of the conductive porous body in the state of maintaining contact with the gas supplying layer. The part on the other surface side of the conductive porous body has no gas supplying layer and forms at least part of the gas chamber in the exposed state.

摘要： PURPOSE:To provide an electrolytic reduction method of gases capable of eliminating the influence of the oxygen coexisting in the gas to be reduced and simplifying the structure of an electrolytic cell. CONSTITUTION:Gas diffusing electrodes 6, 7 are used as anode and cathode and the gas 9 which is to be reduced and into which hydrogen is incorporated is supplied to both gas diffusing electrodes to effect electrolysis, by which the oxygen coexisting in the gas to be reduced is brought into reaction with hydrogen and is removed in the form of water and the gases supplied to the anode and the cathode are made the same. The hydrogen oxidation reaction with which the anodic reaction does not affect the cathodic reaction is attained.

摘要： PURPOSE:To operate an electrode with a smaller quantity of bubbles and high current density by providing plural hydrophilic parts horizontally extending and vertically separated on the surface of a water-repellent gas diffusion layer provided on a reaction layer. CONSTITUTION:A bubble collecting type gas diffusion electrode is constituted by joining a reaction layer 1 including a platinum catalyst and a water-repellent gas diffusion layer 3 through which a current collecting net 2 is inserted. The gas diffusion electrode is immersed in a electrolyte, and bubbles discharged and mixed into the electrolyte are collected on the surface of the gas diffusion layer 3, and diffused into it, and as reaction gas, cause a cell to be operated. In the bubble collecting type gas diffusion electrode, the gas diffusion layer 3 is made to have such a water repellency that the contact angle with water is >=90 deg., and also plural hydrophilic parts 4 having

摘要： PURPOSE:To induce only the prescribed chemical reaction by providing reaction layers with two layers of catalysts of different metals and imparting selectivity to reaction by the kind of the metal of the catalyst layer of the second layer. CONSTITUTION:The plural reaction layers 2, 3 individually deposited with the catalysts of the different metals are joined to one surface of a gas diffusing layer 1, by which a gas diffusing electrode 4 is formed. The oxidation of gaseous H2 and reduction of gaseous O2 are induced by the catalyst layer of the first layer 2 by a local battery reaction when this electrode 4 is used for an electrochemical reactor. The specific oxidation reaction or reduction reaction is induced on the catalyst of the second layer 3 by the transfer of the charges generated at this time. The selectivity is imparted to the reaction by the kind of the metal of the catalyst layer of the second layer 3, by which the specific resulted product of the chemical reaction is obtd.

The heavy water containing LiOD is sealed in an electrolytic bath 5 as an electrolyte 6, silicone oil is fed into the negative electrode 3 as a heat medium, and the electrolysis reaction is controlled to increase the heavy water storage speed and the storage quantity while the temperature of the negative electrode 3 is controlled. A temperature difference is generated between the inner periphery and the outer periphery of the negative electrode 3 through silicone oil, the heavy hydrogen density is increased on the low temperature side to generate nuclear fusion reaction, and the generated excessive heat is extracted to the outside via the heat medium.
