SYSTEM TO MANAGE WATER AND FUEL FOR DEAD-END MODE PEM FUEL CELL

摘要

Disclosed herein is a system for managing water and fuel in a polymer electrolyte membrane fuel cell operated in dead- end mode. In the system for managing water and fuel in a polymer electrolyte membrane fuel cell operated in dead-end mode, a fuel cell system operated in dead-end mode in which an anode to which fuel is supplied and a cathode to which oxidizer is supplied are formed, and a polymer electrolyte membrane is formed between the anode and the cathode, and which is operated in a state in which a exhaustion flow path of the cathode is interrupted, the system comprises a pulsator means connected to an exhaustion flow path of the cathode for generating pulsation having predetermined amplitude and period at the cathode; a voltage measurement means for measuring voltage generated at the fuel cell; and a controller for controlling the amplitude and period of the pulsator means. According to the present invention, there are advantages in that water accumulated in the interior of the fuel cell is exhausted thereby preventing loss in fuel and oxidizer and enhancing the efficiency of the fuel cell.
