摘要： In an electrochemical device of an embodiment, a cell stack has a spacer disposed to be arranged next to an insulating sealing member in a direction orthogonal to a stack direction. A plurality of the spacers are arranged in the stack direction between a pair of end plates, and the spacer is interposed between a pair of separators adjacently arranged in the stack direction. The spacer is formed of a material whose thickness reduction ratio when an operation of the electrochemical device is executed is smaller than that of the insulating sealing member. Before the execution of the operation of the electrochemical device, the thickness of the spacer is thinner than the thickness of the insulating sealing member. Further, the thickness of the spacer keeps a state of being equal to or less than the thickness of the insulating sealing member when the operation of the electrochemical device is executed.

摘要： To provide an electrochemical device capable of sufficiently ensuring sealing performance, and the like. The electrochemical device of this embodiment has an electrochemical cell with an electrolyte membrane interposed between a hydrogen electrode and an oxygen electrode; a plurality of separators formed of a metal material; and gas-sealing materials that seal at least one of between the electrochemical cell and the separator and between the plurality of separators. In the electrochemical device, diffusion-preventing coatings, which prevent diffusion of metal elements in the metal material composing the separators, cover surfaces of the separators. The diffusion-preventing coating is formed of a material that reacts with a material composing the gas-sealing material. There are portions where the separators are in direct contact with the gas-sealing materials.

摘要： To provide an airflow generation device in which dielectric substrates and electrodes are strongly bonded by chemically crosslinking through chemical bonds, which efficiently and homogeneously generates an airflow by plasma discharge between electrodes sandwiching a dielectric substrate, has excellent bendability, heat resistance, weather resistance or light resistance, does not peel off, is not disconnected, and is not destroyed.
The airflow generation device 1 has a first dielectric substrate 15 made from a rubber elastic material, a first electrode 16 provided on or near by a first surface 15 up of the first dielectric substrate 15, a second electrode 14 provided on a second surface 15 down , and a second dielectric substrate 13 made from a rubber elastic material covering the second electrode 14. It makes the airflows generated by plasma caused from partial gas near by the first surface 15 up through applied voltage into the first electrode 16 and the second electrode 14. And bonding portions between the first electrode 16 and the second electrode 14 and the first dielectric substrate 15, bonding portions between the second electrode 14 and the second dielectric substrate 13, and bonding portions between the first dielectric substrate 15 and the second dielectric substrate 13 are bonded by chemical bonds with chemically crosslinking.
