Numerical investigation of solid oxide fuel cell performance

Solid oxide fuel cells are efficient devices to supply electric power and heat, especially for stationary applications. However, degradation mechanisms, poor electrode optimisation and costly manufacturing processes limit their applicability. We apply first-principle models, based on species and charge balances, to describe the interplay between electrochemical phenomena, degradation mechanisms and microstructure, from powder preparation to electrode performance.

Main activities on this topic:

  • electrochemical simulation of electrodes and single cells, from 1D to 3D
  • physically-based simulation and interpretation of electrochemical impedance spectroscopy (EIS)
  • generation and analysis of advanced electrode micro/nano-structures for improved power density
  • numerical investigation of nickel coarsening and redox cycling
