Abstract

By covering the inner circumferential surface of an outer cylinder with a vapor film, thermal conductivity is reduced and the phenomenon of sudden temperature increases in the cylinder wall of the outer cylinder can be prevented, thereby preventing heat damage to the outer cylinder. Additionally, burner burnout, caused by insufficient cooling resulting from irregularities in cooling efficiency at the burner tip, is also prevented. A tip, which is positioned inside a two-stage entrained-flow bed coal gasification furnace, has a double-walled cylindrical structure with an outer cylinder and an inner cylinder, and is configured so that cooling water to cool the tip is supplied via the inside of the inner cylinder and, after cooling the tip, is returned to the base end via the space formed between the outer cylinder and the inner cylinder, and is additionally configured so that the flow path surface area of the space formed between the outer cylinder and the inner cylinder is less than the flow path surface area formed inside the inner cylinder, thus configured so that a swirling flow along guides formed on the outer circumferential surface of the inner cylinder, and a roughly linear flow in the lengthwise direction of the outer cylinder and the inner cylinder, are imparted to the cooling water that is returning to the base end via the space formed between the outer cylinder and the inner cylinder.

Abstract

In a SiCpn diode, the lifetime is controlled by applying an electron beam of approximately 3×1013cm-2 or more. As a result of the life time control, as shown by a current-voltage characteristic (K10) in Fig. 1, the current started to flow from approximately 32V, and the on-voltage at 100A is 50V in the SiCpn diode. At such time, the SiCpn diode has a resistance of 0.5Ω when the diode is turned on. The conducting region of the SiCpn diode is 0.4cm2, and is reduced to 0.2Ωcm2 by increasing the on-resistance by the lifetime control. Therefore, for instance, in an electric circuit device used by connecting a diode and a resistor in series, the resistor can be eliminated.

Abstract

Intended is to prevent such plastic deformation of a separator, as might otherwise be caused by the heat cycle of a fuel cell, thereby to prevent the breakage of a power generating cell. The power generating cell (5) and the separator (8) having reaction gas passages (11 and 12) are alternately laminated in plurality. In the outer peripheral portion of that laminate, there are formed a fuel gas manifold and an oxidizer gas manifold, which communicate in the laminating direction with the gas passages (11 and 12) of the separator (8). The laminate is weighted in the laminating direction. The separator (8) is equipped with an inter-connect portion (8a) having the power generating cell (5) arranged at the central portion, and a pair of arm portions (8b) extended from the edges of the inter-connect portion (8a) and connected at their individual ends (8c) to the fuel gas manifold and the oxidizer gas manifold. The arm portion (8b) is made so flexible as to be displaced in the laminating direction, and its deformation is kept within an elastic range for the heat cycle period.

Abstract

A solid oxide fuel cell structured so that an oxidizer gas and a fuel gas are fed to each of multiple power generation cells disposed in parallel relationship through an oxidizer gas passageway and a fuel gas passageway having diverged from each other in a separator. In this structuring, as the gas seal points of the separator can be limited to two points consisting of an oxidizer gas hole and a fuel gas hole, the seal structure of the separator can be simplified. Further, there is provided a solid oxide fuel cell comprising an exhaust gas flow channel disposed in a stack interior so that any exhaust gas resulting from power generation reaction flows in the direction of stacking, wherein the rate of gas flow toward one side along the stacking direction in the exhaust gas flow channel is greater than that toward the other side. In this construction, by virtue of the exhaust gas flowing along the stacking direction in the stack interior, not only is the mid portion of the stack deprived of heat to thereby attain temperature lowering but also the end portions of the stack are heated to thereby attain temperature rise. Accordingly, the temperature distribution along the stacking direction of the stack can be uniformized.

Abstract

Provided is an ultrasonic inspection method using a transmission probe (31) and a reception probe (32) for transmitting and receiving wide-band ultrasonic waves. Each time the individual probes (31, 32) are moved in their arranged positions, a received wave (Gj(t)) is obtained to extract a narrow-band spectrum (FAj(f)) from a spectrum (Fj(f)) corresponding to the received wave (Gj(t)). A component wave (GAj(t)) corresponding to the narrow-band spectrum (FAj(f)) is determined by an inverse transformation of Fourier. A first-order resonance frequency (f1) of a longitudinal wave on the thickness (W(mm)) of an object (30) and a first-order resonance frequency (fS1) of a transverse wave generated by a mode transformation are calculated. These values (f1 and fS1) and sizing coefficients (ns1, ns2, ns3, ns4) for highly precise inspections are used to compare and display the component wave (GAj(t)). On the basis of the measurement point of the wave in the comparison screen of the component wave (GAj(t)), it is decided that a flaw (Z) is anywhere in the object (30) just below a segment joining the centers of the transmission probe (31) and the reception probe (32).

Abstract

A solid oxide fuel cell of long lifetime in which good electric conductivity can be maintained between power generation cells even after long time use. A protective plate (20) composed of Ni or Cu is bonded to a side of a metal separator (8) on the side of a fuel electrode layer (3) by diffusion bonding. Since a fuel gas does not intrude into the joint of the both members and Ni and Cu are significantly excellent in high temperature oxidation resistance, the separator (8) is surely protected from the fuel electrode atmosphere and growth of a high temperature oxidation coating is blocked. Consequently, excellent electric conductivity can be maintained when the fuel cell is used for a long time.
