Non-Contact Eddy Current Method for Assessing Proton Conductivity in Nafion Membranes

Research output: NLRPoster

Abstract

Accurate measurement of proton conductivity in Proton Exchange Membranes (PEMs) is vital for fuel cell performance and durability. This study explores eddy current testing as a non-destructive, non-contact and high-rate quality control (QC) method for measuring Nafion membrane proton conductivity, with potential for high-volume manufacturing applications.
