Diagnosis and prognosis of proton exchange membrane fuel cells

Abstract : Chapter 10, “Diagnosis and prognosis of proton exchange membrane fuel cells”, by Z. LI, Z. ZHENG and F. GAO, deal with the diagnostic and prognostic issues of fuel cell systems, especially the proton exchange membrane (PEMFC) type. Firstly, the basic functioning principle of PEMFCs and their current development and application status are presented. Besides the high system cost, low reliability and durability constitute two key barriers for their commercialization. In the following section, the degradation mechanisms related to both the ageing effect and the system operations are analyzed. In addition, typical variables and characterization tools, such as polarization curve, electrochemical impedance spectroscopy (EIS), linear sweep voltammetry (LSV) and cyclic voltammetry (CV) are introduced for the PEMFC degradation evaluation. Various diagnostic and prognostic methods in the literature are further classified separately according to the existence of an input-to-output process model of the system, namely model-based, data-driven and hybrid methods. Finally, two case studies for diagnosis and prognosis are given at the end of each part to give the readers a general and clearer illustration of these two issues.
