Abstract: A fuel cell system and a method of controlling the same are provided. The fuel cell system includes a supplying pipe that supplies hydrogen and air to a stack and a gas concentration sensor that senses hydrogen and air impurities supplied to the supplying pipe. A supplying valve is disposed in the supplying pipe to adjust the hydrogen and air supply and a discharging pipe discharges the hydrogen and the air from the stack. A discharging valve is disposed in the discharging pipe to adjust the discharging of the hydrogen and the air. A controller operates with the gas concentration sensor to detect introduction of the impurities. Exhaust valves are disposed at the front and rear end of the stack to remove a polluted fuel when the impurities are introduced. When performance deteriorates due to the impurities, a cause of deterioration is determined, and stack performance is recovered.

Abstract: A membrane electrode assembly and a method of manufacturing an electricity generating assembly include a pair of gas diffusion layers disposed on both surfaces of the membrane electrode assembly. Coupling agents are applied on surfaces of the gas diffusion layers, modifying surfaces of the gas diffusion layers. A coupling agent-friendly adhesive is applied to the surfaces of the gas diffusion layers to which the coupling agents are applied, forming adhesion layers on surfaces of the gas diffusion layers. The gas diffusion layers are stacked on the surfaces of the membrane electrode assembly, causing the adhesion layers to come into contact with the first and second surfaces of the membrane electrode assembly.

Abstract: A device and a method are provided for controlling an operation of a fuel cell system to improve a momentary output of a fuel cell system and decrease a performance deviation between fuel cells. The device momentarily reduces a cell voltage of a fuel cell or changes a fuel cell system to a state close to a shut-down, return the fuel cell system to a normal condition again, and then enable the fuel cell system to be operated normally by applying the “saw-tooth phenomenon” and the “hysteresis phenomenon.” Thus, a momentary output of the fuel cell system is improved to performance of a highest output level or more expressible in a previous state and a performance deviation between fuel cells is decreased.
