Comparison between voltage and current boundary conditions in PEMFC model

摘要

With an aim of optimizing the points of operation of the proton exchange membrane fuel cell (PEMFC), it is better to understand the working procedure with the physical effects and to seek a prediction of the behaviour of this type of fuel cell. This work presents a comparison of the numerical results obtained using two different boundary conditions (current density and voltage boundaries) for the charge transport equation by using a 2D static model of a single cell.
