Title: Manufacture of electrode for fuel cell
Inventor: NOMOTO HIDEYUKI
IPC: H01M4/88
Filed: 1993-08-10
Abstract: PURPOSE:To provide an electrode catalytic layer, which can be effectively adhered to a base material in a condition where a catalytic particle and a PTFE powder are dispersed, and which does not cause a crack. CONSTITUTION:A liquefied CO2 13 is picked up from a cylinder 12 into a container, and fine grain dry ice 14 is provided. Catalytic powder 15 for which Pt is carried on a carrier of carbon black and the powdered dry ice 14 are put in a container 18 in which a liquid N2 17 is preliminarily stored, and are stirred and mixed together, to form a slurry 19. A frame 21 is put on a carbon base material 20 and the slurry 19 is poured thereinto. The material is left until gasification of residual liquid N2 17 and sublimation of the powdered dry ice 14 occur. The frame 21 is removed and a predetermined level of heating and pressurization are carried out to provide an electrode for fuel cell. In this structure, since the liquefied gas is used, few impurities remain, while the dry ice and the liquid N2 can be easily removed by natural gasification, leaving preliminary treatment work unnecessary. Since a hole is formed on the sublimated place, an electrode catalytic layer can be provided without causing a crack.

Abstract: PROBLEM TO BE SOLVED: To obtain a navigation apparatus enhanced in accuracy when the position of a vehicle on a road is to be found. SOLUTION: When a vehicle changes its advance direction in an intersection or the like, the position of the vehicle is estimated. When the position is estimated, and oval-shaped running error range, which is long in the advance direction is set on the basis of an accuracy error generated by a distance error caused by a vehicle speed sensor and by a direction error caused by a direction sensor (S1). In addition, a DGPS error range which is measured by a DGPS system is read out from a DGPS receiving device (S2). Then, a range in which the running error range is overlapped with the DGPS error range is computed, it is used as a vehicle existence range, intersections which exist inside the vehicle existence range are extracted, and they are used as passage intersection candidates (S3). Then, only one passage crossing is decided out of the passage intersection candidates existing inside the vehicle existence range (S4). When a plurality of passage intersection candidate exist, the candidate which is the closest to the center of the DGPS error range is adopted.
