摘要： PROBLEM TO BE SOLVED: To provide a reversible cell for hydro electrolysis and a fuel cell which can resolve the problems in machining/assembling dimensional accuracy associated with size increase and attain cost reduction, by adopting a flexible structure for a bipolar plate which is an important component part in the size increase and high performance of the reversible cell. SOLUTION: The reversible cell includes at least one set of constitutional unit, consisting of a bipolar plate 1/a gas diffuser 2/an MEA 3/a gas diffuser 2/a bipolar plate 1, and the unit is sandwiched and pressurized by end plates 5. The polar plate 1 is a 0.2-3 mm thin-plate titanium or titanium alloy plate, molded by the superplasticity machining method. Mechanical damages to the gas diffuser and the MEA are reduced, and stable performance of the reversible cell over long term can be attained. When this constitutional unit is sandwiched and pressurized by the end plates, dimensional deviation of the gas diffuser or the MEA is absorbed due to the elastic effect of the bipolar plates, and the entire surface contact can be attained at a low pressure. As a result, the mechanical damages to the gas diffuser or the MEA are reduced, and the stable performance of the reversible cell in the long term can be attained. COPYRIGHT: (C)2004,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To safely surely conduct the switching over of an operation mode and realize efficient operation in a reversible cell in which a solid polymer type water electrolytic device and a fuel cell are integrated. SOLUTION: In the reversible cell 1 in which the solid polymer type water electrolytic device and the fuel cell are integrated, when the operation mode is switched over from water electrolytic device operation to fuel cell operation, inert gas is supplied from an inert gas supply source 31 to a passage of the inside of the reversible cell 1, and the inside of the reversible cell 1 is dried. A drying state is judged based on increase in resistance between current supply and collecting plates 2, 3 by an alternate current resistance measuring instrument 35, and after a resistance increased value reached an appropriate extent, a control device 34 stops the supply of gas, and then the operation of the fuel cell is started.

When the film is treated with the acid solution or alkaline solution, the film is followed by washing with a deionized water. The film is kept humid until the film is used at a temperature not higher than that when the treatment of the film is finished in either case. COPYRIGHT: (C)2007,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a high activity long life electrode for oxygen generation which is used for electrolysis of an aqueous solution containing chlorine ion represented by sea water to generate oxygen while suppressing the generation of chlorine and has an intermediate layer containing platinum group metal oxide and formed on a titanium electrode substrate and a conductive coating film of Mn-Mo-W multiple oxide of an anode active material formed on the surface by an anode electrodeposition method and is capable of high oxygen generation efficiency even in the long period electrolysis at high curent density.
SOLUTION: Before the intermediate layer is formed on the titanium electrode substrate, an oxide coating film on the surface is removed by treating with hydrofluoric acid and successively etched with concentrated sulfuric acid to enhance the surface roughness. Because the platinum group metal oxide forming the intermediate layer is entered into projecting and recessed parts produced on the surface of the titanium electrode substrate by the etching to increase the adhesiveness, the peeling of the anode active material from the electrode substrate is prevented to attain long electrode life.
