A fuel cell is an electrochemical system, which converts chemical energy into electricity by a controlled reaction of hydrogen and oxygen. The performance of the electrode is likewise determined by its material and the microstructure.

The simulations were performed directly on reconstructions of real electrodes, obtained from focused ion beam (FIB) tomography. A finite element method (FEM) mesh for the simulations is generated by using the commercial software Simpleware.
