    Abstract

    A model of one dimensional fuel cells is investigated, where the material inhomogeneities in the cathode are taken into account. We use the results in some preceding studies to describe the dynamics of the chemical reactions and transport of ions. A corresponding governing equation is derived for the numerical simulations. We apply an explicit-implicit time integration and Richardson extrapolation technique to increase the accuracy of the approximations. The efficiency of the method is demonstrated using a non-trivial test problem with real parameters. Numerical simulations are executed in presence of inhomogeneous conductivities and their effect on the cell potential is investigated.
