Electrochemical noise analysis of a PEM fuel cell stack under long-time operation: noise signature in the frequency domain

Electrochemical noise analysis of a PEM fuel cell stack under long-time operation: noise signature in the frequency domain

Electrochemical noise (EN) generated by a PEM fuel cell stack (600 W, 8 cells with surface area 220 cm 2 ) has been measured in well-controlled operational conditions following DOE recommendations for 100 h. For the first time, robust and stable statistical noise descriptors of a PEM fuel cell stack...

Zusammenfassung:Electrochemical noise (EN) generated by a PEM fuel cell stack (600 W, 8 cells with surface area 220 cm 2 ) has been measured in well-controlled operational conditions following DOE recommendations for 100 h. For the first time, robust and stable statistical noise descriptors of a PEM fuel cell stack have been obtained based on PSD (power spectral density) spectra in the frequency range of 0.1 Hz
