Tiivistelmä
Inverse problems have been becoming an important method for determination of materials properties, size and shape design, identification of the proper boundary and/or initial conditions. In this work we show the application of the inverse method to multi-component electrochemical systems. The basic process operating in these systems is electrodiffusion which can be described by the full form of the Nernst-Planck and Poisson equations for arbitrary initial conditions and Neumann-like boundary conditions. No simplifications like electroneutrality or constant electric field assumption are used. Results for several examples are demonstrated: determination of chloride diffusion coefficient in concrete, optimization of detection limit for ion selective electrodes and determination of EIS spectra using NPP model.
