Abstract

This work analyses the conditioning of single fuel cell assemblies based on different membrane electrode assembly (MEA) types, produced by different methods. The analysis was done by means of electrochemical impedance spectroscopy, and the changes in the fitted resistances of the all the tested MEAs are studied. The ohmic resistances increase in most cases, implying that the proton conductivity of polybenzimidazole (PBI) membrane degrades during the conditioning process. On the other hand, the intermediate frequency resistances generally decrease showing enhancement in cathodic activities during the process.
