    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: A separating plate for a fuel cell includes first and second plates, each provided with a hydrogen channel, an oxygen channel, and a coolant channel. The first and second plates are attached to one another to form a main plate such that the first and second hydrogen, oxygen, and coolant channels compose main hydrogen, oxygen, and coolant channels, respectively. The main hydrogen and oxygen channels are fluidly isolated from each other. Distal ends of the main channels each communicate with a manifold through a communication passageway configured to supply hydrogen, oxygen, or coolant to a corresponding one of the main channels.

    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.
