Analyzing and Modeling of Water Transport Phenomena in Open-Cathode Polymer Electrolyte Membrane Fuel Cell

Water management is one issue that must be surpassed to ensure high membrane proton conductivity and adequate reactant transport in the membrane-electrode assembly (MEA) simultaneously. A well-designed water system based on a comprehensive understanding of inner part polymer electrolyte (PEM) fuel cell. In this work, phenomena MEA PEM cell are analyzed by using mathematical model. The diluted species interface used model ionomer phase catalytic layer domains. molecular flux defined Nernst–Planck equations, including migration Fickian diffusion parameters obtained experimentally for diffusivity mobility drag fully humidified membrane. proposed 1D includes anode gas channel, cathode (GDL), GDL, catalyst layer, exchange activity, conductivity, output voltage predicted changing humidity side
