Fabrication of platinum coating on titanium transport layer for Proton exchange membrane water electrolyzer (PEMWE)

Year: 2025

Type: article

Abstract: Proton exchange membrane water electrolysis (PEMWE) combined with renewable energy sources such as wind, solar, geothermal provides a sustainable solution for green hydrogen production. In structure of a PEMWE, the porous transport layers (PTL) is a key component of a PEMWE. In order to meet the primary requirement of a PEM water electrolyzer, PTL should be corrosion-stable, have good electrical conductivity, and be mechanically stable for operation at differential pressures. Material porous titanium is the most typically used to construct PTL of PEMWE. However, titanium is also oxidized under the harsh conditions of PEMWE. Forming a passive layer of titanium oxide on the surface of titanium greatly reduces the conductivity of titanium. To limit these disadvantages, in this study, a thin layer of platinum was deposited onto the porous transport layers using DC plating technique. The conditions of DC plating were investigated, experimented and evaluated, from which the current density of 3 mA/cm2 for the platinum coating has the best electrical conductivity and corrosion resistance, which contributes to reducing the precious metal content in PEMWE.
