• A high efficient humidifier has been developed in order to simplify PEFC systems. The humidifier exchanges heat and water simultaneously between cathode exhaust and fresh air. The module of humidifier is a stack of unit separators, which includes water permeable membrane. A dew point as high as 67℃ of fresh air prior to cathode was attained. According to an analytical method, improved effectiveness factors were explained by the flow changes and the decrease of separator's thickness. Counter flow is more efficient than cross flow and return flow. A narrow channel decreases resistance of heat and mass transfer while it increases pressure drop. Therefore, the thickness was determined to restrain the maximum pressure drop less than 100mmAq.
