Publication number: 20240120520Abstract: A decrease in output power due to a foreign matter present on a base at the time of forming a thin film solid electrolyte layer is limited, and an increase in yield even when an area of a fuel battery cell is increased, is obtained. The fuel battery cell has a membrane electrode assembly including a lower electrode layer, first and second solid electrolyte layers, and an upper electrode layer formed on a support substrate. An interface between the first and second solid electrolyte layers is flat as compared with an interface between the lower electrode layer and the solid electrolyte layer, and the second solid electrolyte layer has a thickness at which a leakage current between the first solid electrolyte layer and the second solid electrolyte layer is less than an allowable value even when an output voltage of the fuel battery cell is generated.Type: ApplicationFiled: March 31, 2021Publication date: April 11, 2024Inventors: Yoshitaka SASAGO, Noriyuki SAKUMA, Natsuki YOKOYAMA, Koji FUJISAKI, Nobuyuki MISE, Aritoshi SUGIMOTO

Publication number: 20110058682Abstract: The information reproducing apparatus reproduces plural information sources by switching them in a predetermined order, based on the selecting instruction of the user. When the selected information source coincides with the reference source during the switching of the information sources to be reproduced in the order in accordance with the user's selection instruction, the switching of the information sources to be reproduced is inhibited for a constant time. Namely, the reference source is continuously reproduced for the constant time and the user's selection instruction is ignored. Thereafter, when the constant time passes, the user's selection instruction becomes valid. Since the switching of the information sources to be reproduced is temporarily stopped at the reference source, the user can select the desired information source based on the reference source.Type: ApplicationFiled: May 13, 2008Publication date: March 10, 2011Inventor: Koji Sakuma
