Abstract: To provide a method and an apparatus for reforming a hydrocarbon with a prolonged life of an oxygen-permeable membrane and a high recovery rate. The oxygen-permeable membrane absorbs the free energy change, ?G, of a partial oxidation reforming reaction and then converts it into work for oxygen isolation and Joule heat, Q. Here, as seen in Table 1 and FIG. 1, ?G of the partial oxidation reforming reaction is approximately ten times larger than ?H, and further increases as the temperature increases. The generated Joule heat, Q, has to be removed at a high efficiency, and this removal process is achieved by returning a portion of the Joule heat to the system as the entropy change, T?S, of the partial oxidation reaction itself and by steam reforming using the total energy change, ?H.

A control method for the impact type screw fastening device that uses an electric motor as a rotation driving source includes the steps of driving the motor to rotate by supplying current to the motor intermittently so that torque exerted on a load by rotation of the motor becomes like pulses on the time axis, and controlling the current of every time of each pulse so that an increment of every time of each pulse of the torque after the torque reaches a target approach torque TQN that is a first set value becomes smaller than that before it reaches the target approach torque TQN.

Abstract: An electrochemical cell including a proton conductor as an electrolyte with superior stability, particularly against gases containing carbon dioxide, is provided. A proton-conductive electrolyte 21 used for an electrochemical cell 20B was a ceramic having the composition SrZr0.5Ce0.4Y0.1O3??. As the cathode, a thin film of a proton conductor having the composition SrCe0.95Yb0.05O3??was provided on the electrolyte 21 as an intermediate layer 22, and a porous platinum electrode 23c was provided thereon. The anode used was a palladium electrode 23a. A cell 20A including no intermediate layer 22 had a high overvoltage approaching 600 mV at a low current density, namely, 70 mA/cm2. In contrast, the cell 20B, including the intermediate layer 21, had a low overvoltage, namely, about 170 mV, at a current density of 680 mA/cm2.
