A fuel cell power generation system is provided with at least one fuel cell module each of which includes a fuel cell having a fuel-side electrode, an electrolyte, and an oxygen-side electrode; at least one fuel supply line for supplying a fuel gas to the fuel-side electrode included in the at least one fuel cell module; at least one oxidizing gas supply line for supplying an oxidizing gas to the oxygen-side electrode included in the at least one fuel cell module; and a most downstream exhaust fuel gas line through which an exhaust fuel gas discharged from a most downstream module that is disposed most downstream in a flow of the fuel gas among the at least one fuel cell module flows.

Fuel cell power generation system for treating exhaust fuel gas

A fuel cell module comprises: at least one cell stack including a plurality of single fuel cells supplied with a fuel gas and an oxidizing gas to generate power; a sealable housing accommodating the at least one cell stack and forming a power generation chamber inside the housing; a pressure vessel accommodating the housing; and an oxidizing gas supply pipe for supplying the oxidizing gas to the cell stack. At least one pressure equalizing opening is formed in the housing to allow communication between inside and outside of the housing. The at least one pressure equalizing opening includes only one pressure equalizing opening, or a plurality of pressure equalizing openings in which a distance between a pressure equalizing opening in the highest position and a pressure equalizing opening in the lowest position is within 0.1H, where H is a height of the housing.

Fuel cell module and power generation system

A carbon dioxide recovery system for collecting carbon dioxide from an exhaust gas generated in a facility including a combustion device includes: a first exhaust gas passage through which the exhaust gas containing carbon dioxide flows; a fuel cell including an anode, a cathode disposed on the first exhaust gas passage so that the exhaust gas from the first exhaust gas passage is supplied to the cathode, and an electrolyte transferring, from the cathode to the anode, a carbonate ion derived from carbon dioxide contained in the exhaust gas from the first exhaust gas passage; and a second exhaust gas passage diverging from the first exhaust gas passage upstream of the cathode so as to bypass the cathode. A part of the exhaust gas is introduced to the second exhaust gas passage.

Carbon dioxide recovery system, thermal power generation facility, and carbon dioxide recovery method

A plant includes a fuel supply line for supplying high-pressure fuel gas; and at least one expander disposed in the fuel supply line and configured to extract power from the high-pressure fuel gas by expanding the high-pressure fuel gas.

Plant and plant operation method

Provided is a fuel cell capable of reducing the size thereof by reducing the installation space. The fuel cell includs a plurality of cell tubes, a lower tube plate fixing one end portion of the plurality of cell tubes, a gas flow path portion communicatively connected to an electric power generating chamber through the lower tube plate, a fuel discharge header and an air supply passage provided in the gas flow path portion, in which the fuel discharge header is communicatively connected to an interior of the cell tubes on one surface side and is adjacent to the air supply passage on the other surface and a side surface with a metal member interposed therebetween.

Fuel cell module

An interconnector material having a high degree of densification, a unit cell for a solid oxide fuel cell that has a high degree of gas tightness at the contact interface between the electrolyte and the interconnector, and a solid oxide fuel cell having superior reliability are provided in an inexpensive manner. A material for a solid oxide fuel cell interconnector, comprising (SrE)TiO(wherein x satisfies 0.01&#x2266;x&#x2266;0.5, and E represents one or more elements selected from the group consisting of La, Pr, Nd, Sm and Gd) and AlO, wherein the AlOcontent relative to the (SrE)TiOis not less than 2 mol % and not more than 10 mol %.
