Abstract: The present invention provides a molten carbonate type fuel cell comprising two electrodes as anode and cathode, an electrolyte plate and separators in a single unit and a battery of the unit cells stacked. The electrodes comprise a porous plate of an electron-conducting material such as nickel containing particles of ceramics such as magnesium oxide uniformly dispersed therein in an amount of 2 to 29 atomic %, except for the superficial thin portion free of the ceramic particles on the one-side surface of the plate. The electrodes are prepared by mixing a powder of the electro-conducting material with an organic binder under stirring to obtain a slurry or paste, deaerating the slurry or paste to remove entrained air bubbles therefrom, shaping the slurry or paste plate with or without a metal wire net, drying the electrode plate at room temperature and finally firing the plate in a reducing atmosphere.

Abstract: A molten carbonate fuel cell using molten carbonate as an electrolyte, carbonate ions as electric conductor, and feeding a hydrogen-enriched gas to the anode and a mixture of air and carbon dioxide gas to the cathode has its output fall by degrees with operation. It is surmised that one of the causes of this problem is ascribable to the fact that the molten carbonate electrolyte moves during operation to destroy equilibrium in the boundary between the electrolyte and electrodes. After studies for measures against the problem, the inventor found that the output of a fuel cell which has fallen can be improved by shutting off part or all of the raaction gases or reducing their feed for a while, and then restoring. The purpose of the present invention is to offer a high-performance stable-output molten carbonate fuel cell and its operation control method, incorporating the above findings in its operation control system.

Abstract: A unit cell is formed by a plurality of sub-unit cells as a result of dividing each of the electrodes and electrolytic plate into a plurality of parts. That is, the electrodes and the electrolytic plate are each divided into two parts by electrolytic plate support portions projected from the surfaces of separators. The support portions are pressed in contact with the end portions of the electrolytic plate so as to support the electrolytic plate and seal the reaction gas, preventing it from leaking. The electrolyte support portions of the separators can be provided with electrolyte supply paths, through which the electrolyte is supplied and impregnated into the electrolytic plate. The electrolyte can be supplied via the apertures provided in the separators, to the electrolyte supply paths.

Abstract: A fuel cell power plant comprising a fuel cell employing a molten carbonate as an electrolyte, a reformer for reforming fuel into a reactive gas to be supplied into the anode of the cell, an expansion turbine connected to a compressor, a combustor for burning a gas exhausted from the anode and introducing the combustion gas into the cathode of the fuel cell along with a gas compressed by the compressor, and a waste heat recovery system. The power plant is characterized by the provision of another combustor on the passage through which cathode exhaust gas is sent from the cathode to the turbine and a passage for leading a part of the anode exhaust gas to the combustor, whereby unburned gas, included in the anode exhaust gas, is burned with the cathode exhaust gas supplied as oxygen source so that the temperature of the turbine driving gas is raised, as a result, the overall thermal efficiency of the power plant increases.

Abstract: Disclosed is a catalytic reaction process in which a substance in a liquid reaction system is catalytically reacted with a gaseous substance which is hardly soluble in the liquid reaction system in the presence of a solid catalyst of a non-electroconductive, hydrophobic polymeric material, a part of the surface of which is non-compatible with the liquid reaction system or with the liquid reaction system and a product formed by the catalytic reaction.According to this process, mild reaction conditions can be selected and adopted and separation or recovery of the catalyst can be remarkably facilitated. This catalytic reaction process can be applied to various liquid-gas reactions and can be applied especially advantageously to oxidation and reduction of organic substances and inorganic ions for disposal of waste waters and recovery of valuable substances.

Abstract: A waste gas generated in the reprocessing of used nuclear fuel is at first subjected to removal of explosive, gaseous substances such as hydrocarbons and nitrogen oxides, and materials capable of forming the explosive gaseous substances, such as oxygen, and condensible substances such as carbon dioxide, water and ammonia from the waste gas, and then to cryogenic distillation, thereby separating and recovering Kr-85 from the waste gas. As the separation and recovery of Kr-85 is carried out by cryogenic separation after the removal of the substances having a possibility to explode in a cryogenic distillation apparatus and also the removal of condensible substances having a possibility to clog a piping system of the apparatus, the operation of the apparatus is ensured. It is also disclosed that the oxygen and nitrogen oxides can be completely removed by catalytic hydrogen reduction.
