A novel method of modifying electrolyte surface at mesoscale for intermediate-temperature solid oxide fuel cells
Source abstract
Abstract
Abstract A “dimples array” structure at mesoscale is fabricated on yttria-stabilized zirconia electrolyte substrate by spraying deposition. Microstructure and morphology of the mesoscale dimples configuration are investigated via scanning electron microscopy and the results show that the uniform dimples structure is obtained by spray deposition. With the dimples structure on electrolyte surface, the power density of the electrolyte-supported fuel cell is increased by a factor of 2. Electrochemical impedance spectroscopy (EIS) measurements further reveal that the dimples structure reduces the polarization resistance of the cell, resulting in the improvement of cell performance.
