Abstract: An anode-supported button cell has been extensively developed to achieve a great performance for proton conducting fuel cell (PCFC) application due to its great properties at intermediate temperatures (500-800°C) range. Herein in this work, we fabricated an anode-supported button cell using BCZY as the electrolyte, NiO-BCZY as the anode and LSCF as the cathode with our formulation. The cell configuration of NiO-BCZY|BCZY|LSCF anode support was successfully fabricated by a dry-pressed the anode, slurry brush-painting method to prepare a thin film electrolyte BCZY and the layer of LSCF cathode was completed by a spin-coating technique. The cell was subjected to the fuel cell testing by flowing 10% H2 to anode side and stagnant air to the cathode side. Interestingly, this button cell with new composition and low cost of fabrication shows lower polarisation resistance as well as ohmic resistance resulting in high electrical conductivity. Moreover, the microstructure of button cell showed a good adhesion between the three layers with characteristic dense electrolyte layer and a unique porous electrode. The obtained outstanding results indicate that this product is a promising cell for PCFC application.
