摘要： 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.

摘要： In a pre-replacement process, a replacement battery module is provided with a memory effect before being dispatched, by performing at least one of the process of performing a cyclic charge/discharge operation on the replacement battery module while limiting the width of SOC change to an intermediate range, and the process of setting an initial SOC and then letting the replacement battery module stand for a predetermined time in an environment of temperature above normal temperature. This pre-replacement process substantially eliminates the difference between the voltage characteristic of the replacement battery module yet to be used and the voltage characteristic of a battery module having a history of use, thereby achieving a uniform voltage characteristic of a battery pack as a whole.
