Abstract: For planar solid oxide fuel cell (SOFC) designs, ceramic as well as metallic materials are being considered as construction materials for the interconnectors. Compared to the ceramics, mostly compounds on the basis of La-chromite, metallic materials have the advantage of easier fabricability, lower costs as well as higher heat and electrical conductivity. Based on the requirements in respect to oxidation resistance, low thermal expansion coefficient and electrical conductivity of surface oxide scales, Cr-based alloys and high-Cr ferritic steels seem to be the most promising metallic interconnector materials. Whereas Cr-based alloys have recently especially been developed for SOFC application, a large number of ferritic steels are commercially available in a wide range of compositions. However, it seems that the specific combination of properties required for a SOFC interconnector will necessitate the development of a new, specifically designed steel or the modification of an existing commercial st...
TL;DR: In this paper, an interconnector is interposed between the connector of the oximeter sensor and a connector in communication with an oximeter system, which has interconnectors selected to electrically connect the sensor connector and the system connector in a manner to configure the light-emitting diodes in a configuration compatible with the system.
Abstract: An oximeter sensor can be used with multiple oximeter systems. The oximeter sensor includes a first light-emitting diode, a second light-emitting diode and a photodetector. Electrical connections to the anode and the cathode of each light-emitting diode and electrical connections to the terminals of the photodetector are provided on a connector. An interconnector is interposed between the connector of the oximeter sensor and a connector in communication with an oximeter system. The interconnector has interconnection wiring selected to electrically connect the sensor connector and the system connector in a manner to configure the light-emitting diodes in a configuration compatible with the oximeter system. In particular, a first interconnector configures the light-emitting diodes in a common anode arrangement. A second interconnector configures the light-emitting diodes in a back-to-back (anode to cathode, cathode to anode) configuration. Either interconnector may be in the form of a shell having two connectors. Alternatively, either interconnector may be in the form of a flexible cable with connectors at each end.
TL;DR: In this paper, the performance of planar-type solid oxide fuel cells (SOFC) interconnectors was investigated in the presence of Fe-16Cr alloys and showed that the oxide scale grows in accordance with the parabolic rate law.
TL;DR: In this paper, the vaporization of Cr species of a variety high chromium alloys was studied at 800 °C in air using the transpiration method, and the measured release of the different alloys were correlated with the formed outer oxide scales.
TL;DR: In this paper, the authors used the period between 1995 and 1998 to explore if decoupling of natural gas prices from prices of other energy commodities, such as oil and electricity, took place.
Abstract: After opening up of the Interconnector, the liberalized UK natural gas market and the regulated Continental gas markets became physically integrated and the Continental gas price became dominant. However, in an interim period - after deregulation of the UK gas market (1995) and the opening up of the Interconnector (1998) - the UK gas market had neither government price regulation nor a physical Continental gas linkage. We use this period - which for natural gas markets displays an unusual combination of deregulation and autarky - as a natural experiment to explore if decoupling of natural gas prices from prices of other energy commodities, such as oil and electricity, took place. Monthly price data in the period 1995-1998 indicates a highly integrated market where wholesale demand seems to be for energy rather than a specific energy source.
