The performance of protonic ceramic fuel cell is improved by applying the functional layer between the cathode and the electrolyte layer. The functional layer is a composite with the cathode and the electrolyte. By inserting the functional layering utilizing thin film coating, the performance of the cell varied according to the ratio of cathode to electrolyte in composite functional layer. The results of electrochemical impedance spectroscopy and distribution of relaxation times confirmed that the polarization resistance decreases with the introduction of the functional layer. The low polarization resistance is attributed to extended triple phase boundaries at cathode-electrolyte interface.
