Abstract: PROBLEM TO BE SOLVED: To settle an ion conductive component while keeping it in a desired water containing rate by coating an electronically conductive catalyst supporter with electrode paste, followed by removing an organic solvent and settling of the ion conductive component while forcibly moistening the supporter and the paste. SOLUTION: Carbon paper 16, which is previously subjected to a water repellent treatment, is coated with electrode paste. With water 26 reserved inside a reservoir 28, the paper 16 is held by a cover 36 via suspending means 30 with the surface coated with the electrode paste facing upward. Subsequently, when a first heater 24 is driven by a first temperature regulator 22, the water 26 is boiled to forcibly moisten the paper 16 and the electrode paste. At this time, a second temperature regulator 32 is driven, thereby increasing an ambient temperature sequentially or stepwise. Consequently, an organic solvent contained in the electrode paste is removed and an ion conductive component is settled while the content of water contained in the ion conductive component is effectively kept.  After a degreasing treatment, an anion exchanging membrane is integrated with the paper 16 after steam drying.

Title: Current measuring device
Inventor: IDA YOSHIAKI
IPC: G01R15/24
Filed: 1982-01-21
Abstract: PURPOSE:To make the sensitivity of a titled device satisfactory, and also to make it small-sized, by concentrating a magnetic field into the vicinity of the bottom surface of the first groove in which a photocurrent sensor is stored, by the second groove, and also lightening an electric field by providing a shield on the groove. CONSTITUTION:Into a cylindrical metallic vessel 1, gaseous SF6 is charged, and to an electric conductor 2 whose section is circular, high voltage is applied. When a current flows to this electric conductor 2, a magnetic field is generated in the circumferential direction of the electric conductor 2 in accordance with magnitude of the current, but since shields 6, 7 are separated from the electric conductor 2, a magnetic field by the shields 6, 7 is not generated. Therefore, the magnetic field penetrates the shield 6 and passes through the inside of a groove 3. Also, the current flowing through the electric conductor 2 is bent by a groove 4 and is concentrated near a bottom surface 3a of the groove 3, therefore, the magnetic field being near the bottom surface 3a increases. In this way, by a photocurrent sensor 5 provided near the bottom surface 3a of the groove 3 so that the sensitivity direction becomes parallel to the groove 3, the current can be measured with high sensitivity.
