    摘要: This invention relates to a manufacturing method for a solid-electrolyte fuel cell having a three-layer structure and equipped with a fuel-electrode and an air-electrode for its electrodes with a solid-electrolyte sandwiched between them. A mold (4) comprising a material having a property to suck a specified solvent is used. A slurry is made up by mixing a solid-electrolyte powder and an electrode powder to the same solvent as the above specified solvent, and the slurry is poured in turn in the mold to form an electrolyte green body (5) and electrode green bodies (6) and (7). Thereby, a solid-electrolyte fuel cell including no crack and peeling-off in each layer can be obtained easily and inexpensively.

    摘要: A liquid-fuel feed fuel cell disclosed with a unit cell that has a structure in which a negative electrode and a positive electrode are opposed with a polymer electrolyte having a proton conductivity interposed between them. A liquid fuel is supplied to the negative electrode and air is supplied to the positive electrode. The liquid-fuel feed fuel cell has a cell stack where unit cells are stacked. Additionally, an operation monitoring method for monitoring the operation and an operation monitoring device are disclosed. To prevent degradation, the liquid-fuel feed fuel cell has at least one of the following functions: increasing the supply of air or liquid fuel, issuing an alarm, decreasing the output current, and stopping the operation of the fuel cell when it is detected that the potential between the negative and positive electrodes monitored for at least one cell is below a predetermined negative potential.
