Figure 4

I–V curves for the variation of the diffusion coefficient \(D_{\mathrm{{O}}^{2-}}\) in 1D with all other parameters fromTable 1. (a) Variation of the diffusion coefficient over five orders of magnitude. (b) Simulation with a high diffusion coefficient of the oxygen ions \(D_{\mathrm{{O}}^{2-}}=1\times 10^{-10}\,{\text{m}^2\; \text{s}^{-1}}\) and a small cycle time \(t_{\text{{cycle}}}= 1.2\times 10^{-6}\, {\text{ s}}.\)
