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

摘要

PURPOSE: A water and fuel management system for a polymer electrolyte membrane fuel cell is provided to reduce an unnecessary loss of fuel and an oxidizer, and to improve the efficiency of the fuel cell. CONSTITUTION: A water and fuel management system for a polymer electrolyte membrane fuel cell using a dead-end mode comprises the following: a fuel cell system(1) including an anode(11) for supplying fuel, and a cathode(12) for supplying an oxidizer around a polymer electrolyte membrane(13); a pulsating inductor(40) inducing the pulsating with a constant cycle and amplitude on the cathode while being connected with a discharging path(38b); a voltage measurement unit(16) measuring the voltage generated from the fuel cell; and a controller(17) controlling the cycle and the amplitude from the pulsating inductor.
