Title (EN) SPECTRAL-BASED METHOD FOR FUEL CELL FAULTS DETECTION
(FR) PROCÉDÉ BASÉ SUR LE SPECTRE POUR LA DÉTECTION DE DÉFAUTS DE PILE À COMBUSTIBLE
Abstract:
(EN) The present invention relates to a method for detect faults and/or degradation in fuel cell assemblies, analysing the power spectrum density (PSD) of the voltage signal output by a fuel cell assembly during steady-state operations. The method according to the present invention identifies specific faults and/or degradation signatures as different patterns attained by the PSD of the measured voltage signal.
(FR) L'invention concerne un procédé de détection de défaillances et/ou de dégradation dans des ensembles de piles à combustible, par analyse de la densité du spectre de puissance (PSD) du signal de tension émis par un ensemble de piles à combustible pendant des opérations en régime permanent. Le procédé de l'invention identifie des défaillances spécifiques et/ou des signatures de dégradation comme différents motifs obtenus par la PSD du signal de tension mesuré.
