A new article in Science Direct by Ben Millington & Bruno G. Pollet from the EM Fuel Cell Research Group, Centre for Hydrogen and Fuel Cell Research, College of Engineering and Physical Sciences, The University of Birmingham, Edgbaston, Birmingham, B15 2TT, U.K, and Vincent Whipple from Sono-Tek Corporation, 2012 Route 9 W, Milton, New York 1247, USA discusses the ultrasonic spray method for coating NAfion GDLs with Platinum-based ink.
Here is an excerpt from the paper abstract:
“A novel ultrasonic-spray method for preparing gas diffusion electrodes (GDEs) for proton exchange membrane fuel cell (PEMFC) is described. Platinum (Pt) loaded on Nafion®-bonded GDEs were prepared by the ultrasonic-spray method on various commercial woven and non-woven gas diffusion layers (GDLs) at several Pt loadings in the range of 0.40-0.05 mg cm−2.”
