摘要： PROBLEM TO BE SOLVED: To increase the capacity for treating exhaust gas containing hydrogen sulfide by improving gas-liquid contact efficiency by a method in which a packed bed is formed in a microorganism treatment tank in which hydrogen sulfide in exhaust gas from a geothermal power plant is contacted with a reaction liquid containing sulfur oxidizing bacteria, where the exhaust gas is supplied from below the packed bed for gas-liquid contact. SOLUTION: A two-phase fluid (geothermal fluid) 2 from a production well 1 is separated into steam 3 and hot water 5 by a separator 3, and steam 4 is introduced to a steam turbine 6 to generate power. Steam from the turbine 6 is condensed by a condenser 7, and the uncondensed gas 9 of high hydrogen sulfide concentration is introduced into a microorganism treatment tank 10. In a Raschig ring packed bed 13, the gas 9 is absorbed by a reaction liquid 14-1 sprinkled from the upper part through a circulating line 22 to be desulfurized. Next, an acidified reaction liquid 14-2 out of reaction liquids 14 containing sulfur oxidizing bacteria of a sulfobus group is extracted by a circulating pump 15 to be separated into concentrated bacterial body 14-3 and acidic water 12 containing sulfuric acid by a bacteria separating filter 16.

摘要： PROBLEM TO BE SOLVED: To simplify module structure, reduce the number of constituting members and improve output density by forming a fuel chamber between a top plate and a tube plate arranged within a module main body surrounded with a heat insulating material, and installing a reaction tube composed of plural cell tubes so as to pass through the tube plate and face openings of both ends to the fuel chamber. SOLUTION: A cell chamber 10a of a module main body 10 is heated to working temperature, fuel gas 20 such as hydrogen is supplied from a fuel introduction pipe 16, and air 22 of an oxidizing agent gas is supplied from an air supply pipe 19. The fuel gas 20 supplied through the fuel introduction pipe 16 flows in a cell tube 15 from an opening 15a opened in the fuel chamber 13, is used in reaction, exhausted from an opening 15b of the other end, and flows in a cell tube 15 from an adjacent opening 15a. A supply tube of fuel or air is made unnecessary, the number of module constituting members can be reduced, and as a result, the number of seal components and current collecting components can be reduced.

摘要： PURPOSE:To prevent breakage or falling of a cover by providing a release part to release muffler inside abnormal pressure in a delivery muffler composed of a bearing member to form a compression chamber by blocking up the opening edge of a cylinder and the cover installed in the same member. CONSTITUTION:In a rolling piston type rotary compressor, gas compressed in a cylinder flows into a delivery muffler 13 through a delivery port 19 and a delivery valve 20, and is discharged to a compressor housing from annular clearance 33 between a cover 30 and an upper bearing 8 in a condition that a pulsation component is removed there, and is delivered outside from a delivery pipe. In this case, a spring 32 is fitted on an installation bolt 31 of the cover 30 installed on the upper bearing 8. When high pressure is generated in inner space of the delivery muffler 13 due to liquid compression and so on, since the cover 30 rises from the upper bearing 8 against the spring 32, clearance is created between the outer peripheral edge of the upper bearing 8 and the outer peripheral edge of the cover 30, so that high pressure can be dispersed from this clearance.

摘要： PROBLEM TO BE SOLVED: To provide a fuel cell module capable of dispensing with installing a separate reforming device, dispensing with supplying combustion gas by fuel or waste fuel for the heating necessary for a steam reforming reaction, capable of preventing overheat of upper and lower tube plates, capable of realizing weight reduction and cost reduction, and capable of enhancing thermal efficiency by reducing heat dissipation to the exterior. SOLUTION: By disposing steam reforming catalyst 100 in fuel inlet passages within a power generating chamber 1 and/or in positions adjoining the power generating chamber, the heat generated by power generating reaction in the power generating chamber 1 is directly transmitted to the steam reforming catalyst 100 and thus the heat can be effectively utilized for endothermic reaction in the reformation of fuel gas supplied from the exterior. This can enhance the overall energy efficiency of a system. Because the power generating chamber is cooled by the reforming endothermic reaction, thermal load can be relaxed of container structure members supporting the power generating chamber 1 and requirements can be relaxed for the material and size of the structure members.

摘要： PROBLEM TO BE SOLVED: To reduce a dead space inside a module, and enlarge volume energy density by sharing the positive electrode rooms or negative electrodes of respective unit cells when a module is constructed by assembling plural unit cells. SOLUTION: Plural positive electrode unit cells 101 are inserted from the vessel insertion opening 116 of a module vessel 115. By using the module vessel mounting washers 102 of the positive electrode cells 101, a module vessel top lid 114 and the module vessel main body 111 are fastened via a fastening means. Collectors being positive electrodes are combined mutually outside the module vessel main body 111. After the positive electrode unit cells 101 are contained in the module vessel main body 111, narrow gaps are formed between the solid electrolyte 11 of the unit cells 101 and wicks 19, and fused sodium is sucked up so that the outer faces of solid electrolyte rooms 11 are always kept in a wet state by sodium 20. Thereby, a sodium secondary battery whose cell negative electrode rooms are combined is obtained.
