Abstract: An object is to provide a highly efficient and small-sized fuel cell module. To achieve this object, a cell stack 10, a reformer 20, and an evaporator 30 are accommodated together in a casing 50. The reformer 20 and the evaporator 30 are formed as vertical structures independently juxtaposed to each other and are disposed adjacent to the cell stack. The reformer 20 and the evaporator 30 are heated with exhaust gas resulting from combustion of off-gas released from the cell stack 10. Exhaust gas flow paths respectively are disposed to the reformer 20 and the evaporator 30 so as to let the combustion exhaust gas pass through in a vertical direction for heating the reformer and the evaporator. The exhaust gas flow paths of the reformer 20 and the evaporator 30 are connected in series through a connection pipe 60 above the reformer 20 and the evaporator 30.

Abstract: Combustor for a fuel cell capable of avoiding combustion instability and misfire while having a simple structure and capable of being reduced in size. The combustor includes a partially shielding member disposed in a gas channel for oxygen-containing gas passing. The partially shielding member partially shields the gas channel, thereby introducing part of the oxygen-containing gas passing the gas channel into a primary combustion zone formed in the inside area of the partially shielding member while allowing passing of residue of the oxygen-containing gas toward a secondary combustion zone on a downstream side in a gas passing direction relative to the primary combustion zone. A porous ceramic body is held in the secondary combustion zone and is of a ceramic foam having excellent heat resistance and gas permeability and includes an internal channel formed in a central portion thereof and an external channel formed on an outer peripheral side thereof.

Abstract: This is a discharge cell used for an ozonizer. A space where a discharge gap amount is determined between the first electrodes 10 and 10 is formed by stacking a couple of upper and lower first electrodes 10 and 10, constituted by the plate-like rigid body, in both sides with sandwiching a couple of rigid body spacers 20 and 20. In this space, a dielectric body unit 30 that consists of a rigid body of the sandwich structure of sandwiching a second electrode 32 is arranged between glass plates 31 and 31. The dielectric body unit 30 is supported in a neutral position in the space by a plurality of spacers 40, 40, . . . for discharge gap formation that are inserted between the upper and lower first electrodes 10, and forms discharge gaps 50 and 50 in both sides. The minimum discharge gap amount G of 0.4 mm or less is stably secured. It is possible to prevent the damage of a cell component and a pressurizing mechanism.

Abstract: Oxygen gas having a high purity is supplied to an electric discharge type ozonizer to generate ozone. An ozone density is prevented from decreasing without the use of nitrogen gas by adding moisture to the high-purity oxygen gas via a humidifier when the high-purity oxygen gas is supplied to an ozonizer from an oxygen gas source. Through the addition, the moisture volume in the high-purity oxygen gas supplied to the ozonizer is adjusted to be within the range of 0.05-40 ppm.

Abstract: A solid oxide fuel cell capable of increasin a thermal cycle resistance by uniformizin the flow and distribution of the as of air and fuel in cells, wherein a center through-hole and a plurality of peripheral through-holes are formed at the center part of a cell formation plate and at the center parts of gas separator plates, respectively, and a reaction gas passaae is formed at the outer peripheral parts of the gas separator plates.

Abstract: A fuel cell capable of providing an SOFC wherein a thermal cycle resistance is difficult to occur becase of a uniform the flow and distribution of air and fuel gas in cells. When a gas passage hole part having a center through-hole for gas passage provided at the axial center part of a substrate and having a plurality of peripheral through-holes for gas passage disposed symmetrically with respect to the center through-hole is formed, stacked cell substrates can be supported and tightened by the gas passage hole part at the center part. The flows of fuel gas and oxidizer gas can be optimized, and gas distributions can be made uniform. Particularly, temperature distributions can be uniform in radial direction, and a thermal stress due to thermal expansion occur less. A gas separate plate is formed by forming a gas passage pattern by etching both surfaces of a metal substrate.
