Abstract: A method for charging a non-aqueous electrolyte secondary battery, the battery comprising a positive electrode that comprises a lithium-containing composite oxide, a negative electrode, and a non-aqueous electrolyte. The method comprises the step of detecting an open-circuit-voltage of the battery to determine which of voltage regions A, B and C the detected value is included in. The region A is not smaller than a prescribed value X. The region B is smaller than the prescribed value X and larger than a prescribed value Y (Y

Abstract: A method for operating a direct methanol fuel cell is provided. The fuel cell includes a fuel cell main body having a fuel electrode and an air electrode disposed in opposing positions on either side of an electrolyte film. In this method, an aqueous methanol solution is supplied directly to the fuel electrode. A quantity of the aqueous methanol solution supplied is controlled in accordance with an electric current value drawn from the fuel cell main body so as to minimize a quantity of unused methanol within a discharge fluid discharged from the fuel electrode.

Abstract translation: 提供了一种操作直接甲醇燃料电池的方法。 燃料电池包括具有燃料电极的燃料电池主体和设置在电解质膜两侧的相对位置的空气电极。 在该方法中，将甲醇水溶液直接供给到燃料电极。 根据从燃料电池主体抽出的电流值来控制供给的甲醇水溶液的量，以便使从燃料电极排出的排出流体中的未使用的甲醇的量最小化。
