Development of a simple and rapid diagnostic method for polymer-electrolyte fuel cellsjueves, 01 marzo 2018 A simple and rapid diagnostic tool has been developed to analyze the degradation of polymer electrolyte fuel cells. The tool is based on analyzing the changes in the polarization curves of a cell throughout its useful life. The shape of the polarization change curve and its sensitivity to oxygen concentration are unique for each degradation path according to the analysis of a detailed 2-D numerical model of the stack.A simple and rapid diagnostic tool has been developed to analyze the degradation of polymer electrolyte fuel cells.
