| Popis: | In this study, a novel dead-ended PEMFC stack with an inner condensing unit which set in the cathode outlet main channel are proposed. The effects of different operating conditions on the performance of the dead-ended stack with an inner condensing unit were investigated in detail. The results showed that the designed dead-ended fuel cell stack can stably operate with the hydrogen and oxygen under different operating conditions, the condensation of the exhaust gas of the dead-ended PEMFC can improve the output performance and stability. Increasing the stack operating temperature can improve the dead-ended fuel cell stack output performance. In addition, increasing the cell operating pressure can significantly improve the performance of the closed fuel cell, without affecting the stability. The higher the cell operating temperature is, the better the output performance, while the larger the temperature difference between the exhaust gas condensing device and the internal operating temperature of the cell is, the greater the cell performance enhancement is. |
