    • PURPOSE: An apparatus for controlling anode pressure of a fuel cell is provided to prevent temporal lack of fuel at controlling fluctuation of anode pressure, thereby improving operation safety and durability of the fuel cell. CONSTITUTION: An apparatus for controlling anode pressure of a fuel cell branches a fuel supply line(21) for supplying hydrogen as fuel to an anode of a fuel cell stack(10), connects the fuel supply lines in parallel, and has a first pressure control valve(22a) and a second pressure control valve which controls supply pressure of the hydrogen, according to the control signal of the controller(30), to each fuel supply line. The first pressure control valve maintains the hydrogen-supply pressure to a standard pressure of fuel electrode, according to operation power of a fuel cell. The second pressure control valve controls hydrogen supply pressure to be repeatedly changed up and down. [Reference numerals] (10) Fuel cell stack; (30) Controller
