Abstract: An automatic analyzer detects measurement value abnormalities stemming from reaction process anomalies caused by the presence of foreign matter or bubbles. It is determined whether the results of concentration calculation based on light quantity data from multiple target detectors each fall within an applicable determination range. If the results fall within the determination range, an average value of the results of concentration calculation with the target detectors is calculated, and if not, an out-of-determination-range flag is given. A default fluctuation range is retrieved regarding the average value of the results of concentration calculation. The fluctuation range of the results of concentration calculation with the multiple target detectors is calculated.

Abstract: Fuel cells 100 of the invention are operable at a temperature of about 500° C. The unit cell has a solid oxide electrolyte layer formed on a hydrogen separable metal layer. An anode has a catalyst supported thereon to accelerate a reforming reaction of methane. A fuel gas is produced by reforming a hydrocarbon-containing material in a reformer 20. Setting a lower reaction temperature enables production of the fuel gas containing both methane and hydrogen. In the fuel cells 100 receiving a supply of the fuel gas, the reforming reaction of methane contained in the fuel gas proceeds simultaneously with consumption of hydrogen contained in the fuel gas. This methane reforming reaction is endothermic to absorb heat produced in the process of power generation and thereby equalizes the operation temperature of the fuel cells 100.

Abstract: First, a solid-state electrolyte layer that has conductivity for ions of one of hydrogen and oxygen is formed. After that, a dense layer made of an electrode material that has electron conductivity, catalyst activity to accelerate the electrochemical reaction, and a characteristic of allowing permeation of ions and/or atoms of the other one of hydrogen and oxygen is formed on a surface of the electrolyte layer. Then, a fuel cell structure that includes the electrolyte layer and the dense layer is built. After that, the electrochemical reaction is caused to progress by supplying a fuel and oxygen to the fuel cell structure, so that in the dense layer, many micropores extending through the dense layer in the film thickness direction are created due to the generated water that is created between the electrolyte layer and the dense layer.

Abstract: Disclosed herein is an automatic analyzer that can eliminate the generation of air bubbles of dissolved gas in a liquid circulating in a thermostat bath enabling stable photometry. A degasifier for removing the dissolved gas in the liquid and a bypass passage for ensuring a flow rate required for temperature control of the circulating liquid are provided in a passage for temperature-controlled liquid circulating in the thermostat bath. The automatic analyzer can reduce the dissolved gas concentration to a level at which air bubbles of the dissolved gas in the liquid do not appear while maintaining a flow rate required for temperature control of the liquid circulating in the thermostat bath, thus eliminating air bubbles passing through the light flux during photometry and accordingly enabling stable photometry.

Abstract: The invention provides an electrolyte membrane that allows an operating temperature of a solid polymer membrane fuel cell to be raised and an operating temperature of a solid oxide fuel cell to be lowered. This electrolyte membrane can be used in a fuel cell that is operable in an intermediate temperature range. The invention also provides a fuel cell using such an electrolyte membrane. The electrolyte membrane has a hydrated electrolyte layer, and dense layers made of a hydrogen permeable material that are formed on both sides of this electrolyte layer. Both sides of the electrolyte membrane are coated with dense layers. Consequently, evaporation of moisture contained in the electrolyte layer is suppressed, and increase in the resistance of the membrane is inhibited. As a result, the range of the operating temperature of the fuel cell can be enlarged.
