摘要: Abstract A short oxygen plasma treatment applied on yttria-stabilized zirconia (YSZ) electrolyte of a solid oxide fuel cell has effectively improved the adhesion between nanoporous Pt thin film cathode and YSZ electrolyte, which stabilizes electrochemically active nanoscale features at contact interface. After operating 450 °C for 10 h, with surface treated by retained 88.2% current output, increase Rohm is approximately 20% lower in than non-treated YSZ. This because ion incorporation reaction sites usually occurs Pt/YSZ interface preservation
