PEMYH için COMSOL'da Üç Boyutlu Çoklu Akış Modeliyle Altın Oran Yöntemi ile Oksijen ve Hidrojen Giriş Hızlarının Optimizasyonu

A three dimensional (3D), gas-liquid multi-phase flow and transport model in COMSOL Multiphysics has been developed to simulate phenomena a proton exchange membrane fuel cell (PEMFC) with several operational parameters. The effects of changes oxygen hydrogen input velocities on concentration change at electrodes, current density polymeric performance have investigated PEMFC. simulations, made for numerical method, were presented an emphasis the physical fundamental insight afforded by distributions velocity vector, local density, overpotential, water concentrations. Using Golden Section Method, optimization speed vector was based models values. Results showed that computational methods are great harmony. polarization curve, which is used as measure efficiency performance, supportive results. data show power obtained optimum higher, such 92.87%. Compared currently PEMFC, while saving achieved between 4.2% 7.1%, electrical increase 1% 2.4%.
