摘要： Powders of respective metal elements (Mn, Co) constituting a transition metal oxide (MnCo2O4) having a spinel type crystal structure are used as a starting material of the coating film. A film of a paste containing the mixture of the powders is formed on the surface of the interconnector, and with this state, the paste is sintered to form the coating film. In the coating body, a chromia layer including Cr2O3, a first layer including elements of Mn, Co, Fe, Cr, and O, and a second layer including elements of Mn, Co, Fe, and O are provided in this order from the side close to the interconnector at the boundary between the coating film and the interconnector. With this structure, the coating film is difficult to be peeled even if the coating body is placed in a severe temperature change.

摘要： Provided is an SOFC, including a fuel electrode (20), a thin-plate-like interconnector (30) provided on the fuel electrode and formed of a conductive ceramics material, and a conductive film (70) formed on a surface of the interconnector (30) opposite to the fuel electrode (20). The conductive film (70) is formed of an N-type semiconductor (e.g., LaNiO3). The N-type semiconductor generally has the property of exhibiting a smaller conductivity (a current hardly flows) at higher temperature. Therefore, a portion with a higher current density (thus, a portion with higher temperature) in the conductive film (70) in the vicinity of the interconnector (30) has a smaller conductivity (a current hardly flows). By virtue of this action, even though a “fluctuation in current density of a current flowing through the interconnector (30) and an area in the vicinity thereof” occurs for some reasons, the fluctuation can be suppressed.

摘要： A reference voltage is applied from a reference voltage generating circuit to the non-inverting input terminal of an amplifier for supplying a drive voltage to the gate terminal of an NMOS transistor, and the output voltage appearing at the source terminal of the NMOS transistor is divided by a resistor pair and applied to the inverting input terminal of the amplifier. The voltage obtained by adding a voltage equal to or higher than the voltage for sufficiently driving the NMOS transistor to the output voltage appearing at the source terminal of the NMOS transistor is generated by a charge pump circuit and supplied to the amplifier as a power supply voltage. With this configuration, the drive voltage for the NMOS transistor is suppressed to the required minimum voltage while the drive voltage is obtained securely. The power consumption in the amplifier can thus be suppressed.
