Comment on “Fabrication methods for low-Pt-loading electrocatalysts in proton exchange membrane fuel cell systems” [J.-H. Wee, K.-Y. Lee, S.H. Kim, J. Power Sources 165 (2007) 667–677]

Glow discharge sputter deposition of metals like Pt or other materials is around for decades. One of the many advantages of this process is – certain prerequisites given – the good adhesion of the sputtered layers due to the physical assisted deposition. Sputter deposition is attributed poor adherence by Wee et al. [Jung-Ho Wee, Kwan-Young Lee, Sung Hyun Kim, J. Power Sources 165 (2007) 667–677], which asks for some comments.
