Abstract: The interface between electrode and electrolyte has a certain influence on the electrical performance of solid oxide fuel cells.Yttria stabilized zirconia (YSZ) electrolyte substrate with a grid surface is constructed by the dry-pressing and imprinting method in order to analyze the influence of interface optimization on the cell performance.NiO-YSZ anode is coated onto the grid surface of YSZ electrolyte substrate, and La0.85Sr0.15MnO3±δ(LSM)-YSZ cathode is coated on the other side.The prepared single cell sheet with a mesh anode-electrolyte interface is tested for the electrochemical performance and microstructure analysis by mean of SEM.By comparison with traditional cells, the prepared single cell shows higher maximum power densities under the test temperature, and has richer microstructure in the indentation.It is indicated that the optimization of the anode-electrolyte interface at hundreds of micrometers scale can improve the electrochemical performance of single cell.
