    Hydrogen crossover through a membrane is an inevitable phenomenon in a polymer electrolyte membrane fuel cell (PEMFC). Also, the hydrogen crossed over from anode side is directly reacted with oxygen at cathode side. As a result of direct reaction, water is produced and it hydrates the membrane. Thus, the membrane is not dried completely due to the hydrogen crossover and its direct reaction with oxygen. In this study, hydrogen concentration at the cathode outlet was measured with the mass spectrometer under OCV condition when dry N2/H2, Air/H2 and Air/Air were supplied. Then, direct reaction rate and the amount of produced water were calculated. As a result, it was found that the operating temperature is a dominant parameter on direct reaction rate while the flow rate is negligible.
