      abstract     = {The modeling of fuel cells requires the coupling of fluid
                      transport with electro-chemical reactions. There are two
                      approaches commonly used. Firstly, the electrodes can be
                      treated as two planes, where the potential gradient can be
                      considered as being locally one-dimensional. In this case a
                      two dimensional current density distribution is obtained.
                      Secondly, the two electrode layers can be spatially resolved
                      and the protonic and electronic potentials obtained by
                      solving a pair of coupled Poisson equations. The latter
                      approach requires much higher computational resources,
                      because a higher spatial resolution is required and a large
                      set of model parameters is required. On the other hand, much
                      more detailed local information can be obtained by this
                      method. The motivation for this study was to compare the
                      results quantitively with detailed experimental data for a
                      high temperature polymer electrolyte fuel cell with a
                      geometric area of 200 cm2. Both model approaches show very
                      good agreement with measured local current density
                      distributions. The second model is able to provide a deeper
                      insight into the current density variation through the
                      membrane and catalyst layers and reveals points with local
                      extremes. The present results are specific for high
                      temperature polymer electrolyte fuel cells but the
                      conclusions may readily be applied to the modeling of other
                      high temperature fuel cell types.},
