    摘要: An image reading apparatus includes an automatic document feeder, a first reading unit to read a first side of a document fed by the automatic document feeder and to function as a main reading unit, a second reading unit to read a second side of the document fed by the automatic document feeder; and a control unit to operate the first and second reading units in order to perform an ADF two-sided reading mode. The control unit determines a point in time when the main reading unit is changed, based on a frequency in use of the ADF two-sided reading mode, and changes the main reading unit to the second reading unit at the determined point in time.

    摘要: The method of activating a vehicle fuel cell for ensuring maximum performance, improves performance of a polymer electrolyte membrane fuel cell, reduces a hydrogen usage, and has stable performance after manufactured. The method includes: placing a fuel cell in an activation device so as to be activated; changing a humidification state of a humidifier which supplies vapor to the fuel cell and a state of a cooling water; supplying a reactant gas to the fuel cell and maintaining a no-load state; maintaining a load state while changing a flow rate of the vapor and gas supplied to the fuel cell; changing the sate of the fuel cell to the no-load state, and re-supplying the reactant gas to the fuel cell; and comparing data measured when the fuel cell operates in the no-load state and data measured when the fuel cell operates in the load state respectively with a reference value.

    摘要: The present invention provides an apparatus for effectively preventing carbon corrosion from occurring at the cathode of a fuel cell. The present apparatuses include an air blower supplying air from an air supply source to a fuel cell; a fuel cell receiving air from the air blower to generate electricity by a chemical reaction; an air discharge pipe through which residual air remaining after oxygen of the air is consumed for chemical reaction in the fuel cell is discharged; a pressure sensor provided in the air discharge pipe for detecting air pressure in the fuel cell; an air discharge solenoid valve provided in the air discharge pipe for controlling air flow of the air discharge pipe; and a controller controlling operation of the air blower and the air discharge solenoid valve by receiving a signal detected by the pressure sensor wherein the controller detects the air pressure through the pressure sensor to allow the air blower to supply air to the fuel cell until the air pressure reaches a predetermined pressure and then closes the air discharge solenoid valve until the oxygen in the fuel cell is completely exhausted, thereby preventing the formation of hydrogen/oxygen interface at the anode of the fuel cell.
