| Description |
The present study deals with a novel diagnostic tool for fuel and water management problems by analyzing the
harmonics on an operating polymer electrolyte membrane fuel cell. In this method, a low frequency signal is
applied to the fuel cell and the total harmonic distortion contained in the resulting signal is observed under
different conditions. The total harmonic distortion is used to monitor and identify the conditions online such as
anode drying, anode flooding, hydrogen starvation and cathode flooding prevailing in the cell. This is done by
identifying a set of indicator frequencies correspond to the aforementioned critical conditions. Through empirical studies, it is shown that frequency responses lead to a high total harmonic distortion value indicating
critical conditions and provide an accurate diagnostic method to detect an even slightly degraded state. These
results successfully demonstrate the promise of the proposed method in overcoming performance losses by
efficient online monitoring of fuel cells. The relation between the health of the fuel cell and the variations in the harmonics present in the studied signal is characterized and utilized for the diagnostic studies of polymer electrolyte membrane fuel cel
