Voltage control method and system for fuel cell
A method of controlling voltage of a fuel cell includes steps of: determining whether a mode is a high-voltage avoidance mode of the fuel cell; controlling a fuel cell stack voltage to be at a predetermined reference value or less when the mode is the high-voltage avoidance mode of the fuel cell; monitoring individual cell voltages of the fuel cell and determining whether a maximum value of the monitored individual cell voltages exceeds a predetermined individual value; reducing a reference value of the fuel cell stack voltage when the maximum value of the monitored individual cell voltages exceed the predetermined individual value; and controlling the fuel cell stack voltage at the reduced reference value or less. The method and system for controlling fuel cell voltage is provided to secure durability and performance of individual cells of a fuel cell stack.
