    • PURPOSE: A device and a method for determining deterioration of a fuel cell is provided to rapidly deal with the deterioration of an electrolyte film by checking the state of the electrolyte film with regard to a fuel cell stack of the vehicle in real time. CONSTITUTION: A fluorine ion concentration measuring unit(162,167) detects the fluorine ion concentration of a stack effluent exhausted from a fuel cell stack(110). A condenser is installed on the pipe(110c,110d) of the fuel cell stack to condense the exhaust gas from the gas outlet of an anode and a cathode. A pH meter(161,166) detects the pH. A velocity measuring unit measures the velocity of the stack effluent. A controller(140) confirms an electrolyte film of the stack by calculating a fluorine flow velocity. The controller determines the deterioration of the electrolyte film if the fluorine flow velocity is out of the normal range.

    • The present invention relates to a polymer electrolyte membrane fuel cell system and to an operating method thereof. The polymer electrolyte membrane fuel cell system of the present invention includes: a membrane-electrode assembly (100) including a unit cell consisting of an anode (110), an electrolyte membrane (130) and a cathode (150); a fuel supply unit (200) supplying fuel including hydrogen to the anode (110); an air supply unit (300) supplying air including oxygen to the cathode (150); and water supply units (400a, 400b) connected to the exit side of the membrane-electrode assembly (100) so as to supply water and water vapor to the unit cell on shutdown of the system. The polymer electrolyte membrane fuel cell system has an effect of preventing electrode degradation due to reverse potential occurring in the process of shutdown and operation of the system by preventing inflow of air by reducing the pressure difference to the outside by flowing in water and water vapor in to the unit cell on shutdown of the system, and by discharging water stagnated in the flow path, and nitrogen and impurities in inflow air during operation of the system.
