摘要： Disclosed are a hybrid aluminum electrolytic capacitor and a method of producing the same, where the electrolytic capacitor is impregnated in a film repairing fluid. The film repairing fluid includes an organic solvent having a b.p. of 180° C. or more, a small number of an inorganic and/or an organic acid and an amine having a b.p. 180° C. or more. The fluid has high withstand voltage and can provide repairing effect for the oxide film of the anode foil of the non-solid aluminum electrolytic capacitor. The hybrid aluminum electrolytic capacitor impregnated with the film repairing fluid of the invention has the characteristics of high voltage, high capacity, low impedance and small leakage current, so that the electrolytic capacitor can maintain low equivalent series resistance and low impedance in the high frequency range.

摘要： An apparatus for storing hydrogen as protons and electrons separately. The apparatus includes a DC power supply; a hydrogen electrolysis unit including a hydrogen tank adapted to contain hydrogen under pressure and in contact with one or more catalyst electrodes contained in the tank, the one or more catalyst electrodes in electrical connection with the DC power supply; and an electron storage unit for storing electrons, the electron storage unit in electrical connection with the DC power supply and separated from the hydrogen electrolysis unit. In a proton generation mode, the DC power supply is configured to operate the one or more catalyst electrodes in anode mode to catalyze oxidation of hydrogen in the hydrogen tank to form and store protons on or near the one or more electrodes and store generated electrons in the electron storage unit.
