Abstract

Mathematical modeling plays an important role not only in helping us to understand the physiochemical phenomena occurring in fuel cells, but also to design and develop fuel cell systems. This article presents an overview of the mathematical modeling of direct alcohol fuel cells (DAFCs). It starts with an introduction to an empirical model that helps in interpreting experimental data, determining kinetic parameters, and identifying various types of voltage loss. The article then focuses on discussing a steady-state isothermal two-phase mass transport model that considers conservation equations of mass, species, heat, and current transport in various regions of a single DAFC cell.
