A mathematical model to study the performance of a proton exchange membrane fuel cell in a dead-ended anode mode
Yang, Chih-Wei; Chen, Yong-Song - In: Applied Energy 130 (2014) C, pp. 113-121
When a proton exchange membrane fuel cell (PEMFC) system is operated in the dead-ended anode mode, nitrogen will gradually permeate from the cathode to the anode. The accumulation of nitrogen in the anode causes a performance drop, which can be recovered by purging. The purge strategy depends on...
