These generations have to be repeated with varying CBD internal porosity values, obtaining for each of them the tortuosity factor as a function of the total electrode porosity. Afterwards, each tortuosity factor vs. electrode porosity dataset should be fitted to either the Bruggeman equation, its generalized form, or another appropriate model. Comparing the fitting parameters of the simulations to those of the experimental set, the CBD internal porosity that best matches the experimental results corresponds to the one of the real electrode. This microstructure can then be used to simulate the end-application of interest with the certainty that the tortuosity factor will be matching its experimental counterpart.
