| چکیده مقاله |
| PEM fuel cells (PEMFC) are most widely used types of fuel cells for power generation purposes. Increasing fuel efficiency and proper water management are important challenges in a fuel cell system, especially in the dead-end mode. The voltage stability of the purge cells in the dead-end mode strongly depends on the control parameters of the purge valve, such as the valve opening, purge interval, and purge time. In this study, the performance of a 2 kW cascade type PEMFC in the dead-end mode was investigated and the effect of purge parameters on cells voltage variation and overall stack performance was investigated. The results showed that not only efficiency of fuel and oxidant consumption increased with the dead-end operation, but also the cells voltage stability was acceptable. Also during the test, acceptable reproducibility was observed in the amount of exhaust gas as well as the voltage fluctuation of the purge cells. |
