摘要： PROBLEM TO BE SOLVED: To suppress enrichment of oxygen in a space to be dehumidified in a dehumidifier using an electrochemical element, by forming a shielding room in the anode side of the electrochemical element by using a membrane so as to separate the anode from the space to be dehumidified body in the dehumidifier and further forming small holes in the peripheral part of the shielding room. SOLUTION: The anode 1 and the cathode 2 of the electrochemical element E consist of a porous material, and a Nafion (R) film is used for the solid polymer electrolyte film 3. The solid polymer electrolyte film 3 is held between the anode 1 and the cathode 2 and joined by hot press. Feeder bodies 4 are attached to the peripheral part of the electrode faces 1a, 2a of the anode 1 and the cathode 2 to form the electrochemical element E. The electrochemical element E is disposed with the anode 1 facing to the space 7 to be dehumidified, and a shielding room 9 is formed by a membrane 10 which transmits water vapor but does not transmit oxygen so as to separate the electrode face 1a of the anode 1 from the space 7 to be dehumidified. Thereby, increase in the oxygen gas concn. in the space 7 to be dehumidified can be prevented.

摘要： PROBLEM TO BE SOLVED: To surely prevent a large amt. of oxygen from being accumulated in a cabinet by providing a closing lid for closing an opening to keep the cabinet airtight on the anode side or cathode side of an electrochemical element. SOLUTION: A closing lid 12 for closing an opening 3 to keep a cabinet 1 airtight is provided on the anode 5 side of an electrochemical element 4. When the inside of the cabinet 1 reaches a desired humidity, a control signal for closing the lid 12 and a control signal for stopping the supply of power to the element 4 is outputted from a controller 14 based on the detection signal of a humidity sensor 13, hence the opening 3 of the cabinet 1 is closed by the lid 12, and the operation of the element 4 is stopped at the same time. Consequently, the cabinet 1 is kept airtight, the oxygen enriching action due to the water electrolysis on the anode 5 is stopped, the inside of the cabinet 1 is maintained at a low humidity, and the increase in oxygen gas is blocked.

摘要： PROBLEM TO BE SOLVED: To eliminate the danger of hydrogen explosion by the accumulation of the gaseous hydrogen generated from the cathode of an electrochemical device equipped with an electrochemical element held with a solid-state high- polymer electrolyte which is a hydrogen ion exchange membrane between the anode and cathode to which a DC voltage is impressed. SOLUTION: The cathode 3 side of the electrochemical element 1 is provided with a cover 11 for shielding the surface of the electrode surface of the cathode 3 in proximity to this surface. A microspace 12 which fluidizes the gaseous hydrogen generated from the cathode 3 along the electrode surface of the cathode 3 is formed between this cover 11 and the electrode surface of the cathode 3. A catalyst for accelerating the oxidation reaction of hydrogen is deposited on the electrode surface of the cathode 3 or the inside surface of the cover 11 facing the electrode surface. An aperture 13 for admitting air into this narrow space 12 is formed on one end side of the cover 11.

摘要： PROBLEM TO BE SOLVED: To prevent an oil discharged from a main frame from entering the refrigerating cycle, by providing a compressor with a holder which has a male/ female fitting part for fitting with the lower part of a main frame, and providing its upper part with a structure which temporarily receives a lubricating oil which has passed through a rotational part. SOLUTION: A lower part of a main frame 6 has a cylindrical fitting projecting part 6e as a male/female fitting part and a casting tray-shaped holder 20 which has a cylindrical fitting recessed part 20b as a male/female fitting part fitting with the projecting part 6e. The upper part of the holder 20 is equipped with a structure which temporarily receives lubricating oil which has passed through a rotational part and with a discharging 20a. Oil which finishes lubricating a bearing surface 6b of a thrust force collects in the holder 20 through an oil discharging hole 6c which is placed on the mail frame 6, and returns to the lower part of a sealed container 10 through the discharging pipe 20a. Because path for lubricating oil is ensured at each part, lubricating oil 13 is certainly cycled in a compressor, amount of oil entering into a refrigerating cycle is reduced, and amount of stored oil can be kept.

摘要： PROBLEM TO BE SOLVED: To easily confirm a precise oil level of a lubricating oil, by forming the piping upper part and lower part out of a side wall of a sealed container to the outside, and connecting a window attaching member in which the upper part of the window is higher than an upper limit of an oil level of the lubricating oil in the normal condition and the lower part of the window is lower than a lower limit of the oil level of the lubricating oil in the normal condition. SOLUTION: A pair of upper and lower pipes 120 are mounted on the outer part of a sealed container 8 by welding so that ends of the pipes open at the upper and lower positions of a sub-frame 6, respectively. A window attaching member 96 consists of a longitudinal hollow member 96a and a window 96b, upper and lower parts of the hollow member 96a are connected with the other ends of the pipes 120, respectively. The window 96b is placed at a position where the upper part of the window is higher than an upper limit of an oil level of a lubricating oil in the normal condition and the lower part of the window is lower than a lower limit of the oil level of the lubricating oil in the normal condition. Because the window attaching member 96 is pressure-balanced with a low-pressure space (motor-side space) 84 in the sealed container 8 through the pipes 120, the oil level of the lubricating oil dose not oscillate and the oil level position is easily conformed. In addition, whole oil level region of the lubricating oil in the normal condition can be confirmed in the range of the window 96b.
