اثر تخلخل لایه پخش گاز و فشار بر عملکرد پیل سوختی غشا پلیمری با میدان جریان لانه زنبوری

This paper presents a numerical modeling, provides an improved understanding of the fundamental transport phenomena inside the poroton exchange membrane fuel cell(pemfc) with honeycomb flow-field. the problem is stated in a steady-state, three-dimensional model and cartesian coordinates system by using a single domain and a control volume method. the model consists of non-linear, coupled partial differential equations representing the conservation of mass, momentum, species, charges and energy with electrochemical reactions that are valid for gas diffusion electrodes, catalyst layers and membrane region. the modeling of bidirectional, isothermal and steady problem of pemfc with honeycomb flow-field provides results concerning the species fraction and potential distribution in different domain.
