Improving thermal stability of nanoporous platinum cathode at platinum/yttria-stabilized zirconia interface by oxygen plasma treatment
A short oxygen plasma treatment applied on yttria-stabilized zirconia (YSZ) electrolyte of a solid oxide fuel cell has effectively improved the adhesion between the nanoporous Pt thin film cathode and the YSZ electrolyte, which stabilizes the electrochemically active nanoscale features of Pt at YSZ...
