Abstract: PROBLEM TO BE SOLVED: To prevent a dew from being condensed on an inner wall of a test tank while a gas concentration is stabilized by a method wherein a dehumidifier and a circulation pump are arranged from a circulation opening side in a circulation circuit between the circulation opening of a tester and its return opening, and only moisture in a gas atmosphere in the test tank is released to the open air by an ion exchange membrane of the dehumidifier to make a dry gas by dehumidification. SOLUTION: A test gas is adjusted in concentration by dilution and mixing, and introduced into a test tank. A circulation circuit is provided between a circulation opening 16 of the test tank of a gas corrosion tester 2 to be adjusted to the gas concentration atmosphere and its return opening 17, and a dehumidifier 1 and a circulation pump 18 are arranged successively from the circulation opening 16 side. Only the moisture in an exhaust gas is released to the open air through an ion exchange membrane 4 to be dehumidified while it is passed from a gas inlet to an outlet on a side surface of a frame wherein the ion exchange membrane 4 is spread on both sides in the dehumidifier 1, and the product is returned as a dry gas into the gas atmosphere. Control of the circulation pump 18 is executed by a temperature and humidity control mechanism 13. Thereby, a change in a gas concentration to be caused by dissolution of the gas into dew condensed water and dew condensation on an inner wall of the test tank can be prevented.

Abstract: PROBLEM TO BE SOLVED: To plate both surfaces of a membrane with platinum at one time by grinding the surfaces of a membrane to obtain rough surfaces, forming a platinum thin film on each surface by sputtering, heat treating in hot water, treating with a reducing agent in a hydrazine-hydrate soln., and bringing the both surface into contact with a chloroplatinic acid soln. in a fluidized state. SOLUTION: After the surface is polished, the membrane is boiled in boiling pure water for 1 to 2 hours to remove impurities. Argon gas is introduced into a sputtering device, the pressure is adjusted to almost 10 Pa to generate glow discharge between a platinum target and a substrate on which an ion exchange membrane is mounted. Thus, sputtering is caused to deposit platinum atoms on the ion exchange membrane to form a thin film. Then the membrane is heat-treated in warm pure water and reduced in a hydrazine monohydrate (H2 NNH2 .H2 O) soln. Then the ion exchange membrane 1 is held and fastened in plating cells A and B, a chloroplatinic acid (H2 PtCl6 .6H2 O) soln. 5 is supplied through a ventilation port and circulated by a circulating pump D so that the liquid in a fluidized state is brought into contact with the membrane to plate the both surfaces at one time.

Abstract: PROBLEM TO BE SOLVED: To lower the bath voltage and heat loss by using carbon fiber cloth or mat like cloth, on which lead dioxide is electrodeposited, as a lead dioxide catalytic body in an anode side. SOLUTION: The carbon fiber cloth 6 is obtained by plane-weave single fiber formed by bundling several thousand numbers of superfine carbon fibers into a cloth like form, cutting, dewaxing in a dewaxing bath, washing and drying. The carbon fiber cloth 6 is applied on a platinum net made conductive belt 8 attached along the periphery of four sides of an electrically insulating material made square frame 7 so as to be in uniform contact and held by a pressing frame 9 to be fixed. The square frame 7 is dipped into an electrolytic bath housing a solution prepared by dissolving lead (II) tetrafluoroborate in a prescribed concentration, a platinum plate is dipped in a position opposed to the square frame 7 and the platinum net made conductive belt 8 and the platinum plate are connected to respectively an anode and a cathode of a DC power source to apply current to obtain the carbon fiber cloth 6 having lead dioxide electrolytically deposited uniformly on the surface. In the assembly of an electrolytic cell, the carbon fiber cloth 6 is applied on the surface of the high molecular solid electrolyte and pressed with a porous electrode to be used.

The two daces of exchange membranes in an ion-exchange membrane dehumidifier 9 are opposed to each other hold a square frame of the same size between them and are fixed close to the frame, perforated plates are piled up to protect the exchange membranes, dry air 5 or gaseous nitrogen is hit against the membrane and the moisture in the gas is passes through the membrane and discharged. A double-cylinder type exchange-membrane dehumidifier is also preferable as the dehumidifier.
