Key Points

  • To investigate how TiN interlayers improve the durability and performance of Pt-coated titanium transport layers in PEM water electrolysis.
  • Utilized TiN interlayers in Pt-coated Ti-felt porous transport layers (PTLs)
  • Applied 120 W Pt sputtering for optimal morphology
  • Evaluated electrochemical stability and corrosion resistance
  • TiN interlayers significantly improved electrochemical stability of the Pt-coated layers
  • Reduced corrosion rates at TiN/Pt interfaces
  • Increased durability by approximately 80 hours compared to layers without interlayers

Abstract

TiN interlayers enhance the electrochemical stability of Pt-coated Ti-felt PTLs for PEMWE. 120 W Pt sputtering yields optimal morphology; TiN/Pt interfaces minimise corrosion, boost charge transfer, and extend durability by 80 h.
