A two-dimensional, non-isothermal model of a proton exchange membrane fuel cell was formulated by taking the agglomerated catalyst structure into account. Dual-pathway kinetic, i.e. a combination of Heyrovsky-Volmer and Tafel-Volmer kinetics, was employed to precisely describe the hydrogen oxidation reaction. The presented model was validated with cell polarization data taken from experimental data prepared by our previous work, and the agreement was good. Temperature distribution inside the membrane electrode assembly (MEA) was predicted by employing the present model. |
