Abstract

"This work developed a novel method of using Electrodeposition techniques to fabricate metallic gas diffusion layers (GDLs) for application in proton exchange membrane fuel cells. These GDLs improve the electrical and thermal conductivity of the fuel cells, and their straight, noncircular pores remove water efficiently. The Electrodeposition technique used here relies on a sacrificial copper anode and an aluminum sheet 50 µm thick acts as a cathode. Unlike the other laboratory based methods available for the fabrication of metallic GDLs, this method is simple and cost effective. With controlled deposition parameters and a chemical lift-off process that corrodes the aluminum sheet in an acidic environment, it produces copper sheets of l 0-20 µm thick with the required properties. This paper describes the improvements that can be made to the pore size, shape, and function based on changes in the Electrodeposition parameters"--Abstract, page iii.
