摘要

A strategy based on laser micro-processing was proposed to improve the solid oxide fuel cell performance by modifying electrode/electrolyte interface with a “dimples array” structure. Electrochemistry impedance spectroscopy (EIS) results showed that both ohmic and polarization resistance of single cell were decreased remarkably after interfacial modification. Moreover, the maximum power density of modified cell was increased by up to 58% at 800 °C. The microstructural images of electrode/electrolyte interface indicated that the structured interface extended the triple-phase boundary (TPB) length for electrochemical reaction, which led to the major improvement in the cell performance.
