Generation of Statistical Descriptors for Running PEM Fuel Cell Stack by Means of Long-Time Electrochemical Noise Measurements
Electrochemical noise (EN) measurements have been provided with PEM fuel cell stack of 600 W nominal power. These measurements demonstrate that EN can be used as a tool for diagnostics of possible faults in lo...

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 cm2) has been measured in well-controlled operational conditions following DOE recommendations for 100 h. For th...
