    摘要： On each of upper and lower surfaces of a flat-plate-like support substrate 10 having a longitudinal direction and having fuel gas flow. channels 11 formed therein, a plurality of power-generating elements A connected electrically in series are disposed at predetermined intervals along the longitudinal direction. On each of the upper and lower surfaces of the support substrate 10, a plurality of recesses 12 are formed at predetermined intervals along the longitudinal direction. Each of the recesses 12 is a rectangular-parallelepiped-like depression defined by four side walls arranged in a circumferentially closed manner and a bottom wall. That is, in the support substrate 10, frames are formed to surround the respective recesses 12. Fuel electrodes 20 of the power-generating elements A are embedded in the respective recesses 12, and inter connectors 30 are embedded in respective recesses 21 b formed on the outer surfaces of the fuel electrodes 20. In this manner, there can be provided a structure of a "segmented-in-series type" fuel cell in which, when a support substrate is subjected to an external force, the support substrate is unlikely to be deformed, and in which the electron conductivity between the fuel electrodes and the electrical connections is high.

    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., LaNiO 3 ). 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： An electrochemical apparatus has a plurality of ceramic electrochemical cells 1, a plurality of gas feed members 4A and a plurality of gas discharge members 4B. The electrochemical cell 1 has a first electrode 6 contacting with a first gas, a solid electrolyte layer 15 and a second electrode 12A, 12B contacting with a second gas. A gas flow channel 5 for flowing the first gas therethrough, a first through hole 8 and a second through hole 9 are provided in the electrochemical cell 1. The gas feed member 4A is inserted into the first through hole 8, the gas discharge member 4B is inserted into the second through hole 9. The adjacent gas feed members 4A are airtightly coupled to each other to thereby form a gas feed channel, and the adjacent gas discharge members 4B are airtightly coupled to each other to thereby form a gas discharge channel.
