摘要： [Object] To provide a gas decomposition apparatus and a gas decomposition method in which no safety problems occur in spite of the application of a relatively high voltage between an anode and a cathode for the purpose of decomposing odorous gases of many types.[Solution] A catalytic electrode layer 6 that contains a catalyst and is porous; a counter electrode layer 7 that forms a pair with the catalytic electrode; and an electrolyte layer 15 that is sandwiched between the catalytic electrode and the counter electrode and has ion conductivity are included. The catalyst is held by the catalytic electrode in the form of being carried by a carrier containing a conductive material or the catalyst is directly carried by the catalytic electrode. A conductive material in the catalytic electrode, the conductive material being in contact with the catalyst, is not a noncovalent carbon material.

摘要： Provided is a terminal-attached electric wire including: an electric wire having a conductor made of aluminum or an aluminum alloy whose outer circumference is covered with an insulating layer; and a terminal member made of copper or a copper alloy and attached to a conductor-exposed portion exposed from the insulating layer at an end portion of the electric wire. The terminal member includes a coating layer made of an electrically conductive material and formed at a terminal-exposed portion except for a place of contact with the conductor in a surface of the terminal member, and an oxide film of the electrically conductive material formed in a surface of the coating layer. The electrically conductive material is a metal or an alloy which forms an oxide film having a thickness of more than or equal to 20 nm in a surface thereof.

摘要： Provided is an electrolyte flow battery system including a gas supply mechanism that always continuously supplies a flow gas containing an inert gas to a gas phase in a tank that stores an electrolyte. In the electrolyte, the total concentration of ions of elements in groups 1 to 8 and 13 to 16 in the fifth period and groups 1, 2, 4 to 8, and 13 to 15 in the sixth period of a periodic table is 2,500 mg/L or less. The generation rate of hydrogen is less than 95 cc/h/m2 when a charge and discharge test is performed while the electrolyte is circulated and supplied to an electrolyte flow battery. The flow rate of the flow gas is 1.0 L/min or more and 50 L/min or less.
