Efficient water-related failure detection in PEM fuel cells: Combining a PEMFCs fractional order impedance model with FFT-PWM techniques and artificial neural network classification

Real-time H2S detection kit for hydrogen fuel cell

“…Although PEMFCs are efficient considering the output power and the environmental aspect compared to fossil fuel-based power generators, the lifetime should be considered deliberately [ 14 ]. Although there have been many studies on the durability of the PEMFC systems [ 15 ] and operational parameters optimizations [ 16 ], further attention should be given to the real-time detection of contamination in PEMFC just like similar studies that have tried to mitigate the hydrogen sulfide amount in different applications [ 17 ]. Based on the defined targets by the Department of Energy (DOE), the lifetime of 8000 h at a voltage of 0.8 V and the performance of 300 ( ) is aimed at 2025 [ 18 ].…”
