**4. Simulation Results**

Figure 4 shows a set of polarization curves calculated by the presented model. A variation of the chosen parameters affects the overpotentials and therefore the overall cell voltage (Section 2). In terms of computational time, creating a polarization curve with hundreds of data points only takes a few s on a modern CPU. This shows the suitability of the model at hand for large system simulations or real-time applications. The inputs and most important parameters for the reference case are represented by Table 1, and a complete list of all model parameters is supplied as Supplementary Material.
