A comparison on the dynamical performance of a proton exchange membrane fuel cell (PEMFC) with traditional serpentine and an open pore cellular foam material flow channel

Minimising the pressure drop in flow channels, ensuring high efficiency and utilisation of open pore cellular foam (OPCF) material place a traditional serpentine channel are investigated this work. The paper establishes novel mathematical model that takes into account effect compares dynamics porous with those channel. performance Polymer Electrolyte Membrane fuel cell is analysed under static transient conditions. mass transport equations used also varying current on stack temperature. membrane water content IV-curves simulation results presented based models proposed system using MATLAB®/Simulink® environments. diameter, porosity, velocity sensitivity analysis. Due to lower provided by uniform distribution reactants OPCF channel, an improvement approximately 55% observed density when compared same operating investigation further concluded higher diameter can have reactant does not exceed 6 m/s.
