A new non-invasive method to measure PEFC in-plane membrane conductivity distribution is presented. It is based on electrical impedance tomography that relies on surface current injection and voltage measurement at the outer cell surface. The working principle is detailed and a numerical feasibility study shows the potential of the technique.
