Abstract
The chaotic analysis is often used to investigate electrochemical signals. The proposed work applies it to understand the behavior of hydrogen electrochemical devices, with particular attention to electrochemical hydrogen compressors (EHC). Measurements, carried out at the C.N.R Istituto di Tecnologie Avanzate per l'Energia "Nicola Giordano" of Messina, show a current fluctuation with a fixed voltage. The oscillating phenomenon is not justifiable by the Nernst equation and the possible chaotic behavior of the EHC has been investigated. The system is highly sensitive to the initial conditions and presents a density of periodic orbits, shown in the reconstructed phase plane through the time delay embedding technique.
