    Abstract: PURPOSE: A method for diagnosing malfunction of electrolyte membrane is provided to quickly and accurately detect a state of electrolyte membrane of a fuel cell stack during a normal driving, thereby capable of improving merchantable quality of a vehicle with fuel cell. CONSTITUTION: A method for diagnosing malfunction of electrolyte membrane comprises: a step(S10) of measuring voltage of fuel cell stack from a shutdown of a vehicle with built-in a fuel cell stack(S10); a step(S20) of deriving OCV and time constant by substituting many voltage values through the previous step and measured time of the voltage values; a step(S30) of comparing the obtained OCV and the time constant with a standard OCV and time constant; a step(S40) of judging the electrolyte membrane has damages when the obtained OCV and the time constant are smaller than the standard OCV and time constant. [Reference numerals] (AA) Shutdown(stop the supply of hydrogen and air in a fuel cell stack); (BB) Voltage measurement; (CC,FF) No; (DD) Specific time(4sec)

    Abstract: PURPOSE: A crack detection-molding device of a separator for a fuel battery is provided to prevent faulty cracks of a separator according to abnormal molding conditions and to enhance the efficiency of manufacturing the separator by detecting cracks in a process molding the separator using a molding device on a real time basis. CONSTITUTION: A crack detection-molding device of a separator(1) for a fuel battery comprises an upper die(11) and lower die(21). Gaskets of the upper and lower dies are formed in an edge portion of a processing unit(31) corresponding to a shape of the separator. Crack detecting gas is inserted into the processing unit while molding the separator by uniting the upper and lower dies. Cracks of the separate are detected by measuring a flow rate of the crack detecting gas which are leaked while passing through a cracked portion of the separator.
