“…Compared to the fault diagnosis using fuel cell voltage, more studies have been performed using multiple sensors information [ 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 ]. Both single [ 7 ] and multiple PEM fuel cell faults [ 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 ] can be identified accurately with information from multiple sensors, using either model-based or data-driven approaches.…”
