Corrosion Behavior of Pure Aluminum in the Simulated PEMFC Environment

摘要

The corrosion behavior of pure aluminum in the dilute sodium fluoride and sodium sulfate solutions as simulating the PEMFC environment was studied through immersion process at different time. The corrosion was accelerated in the presence of fluoride ions whereas sulfate ions caused very less amount of corrosion. The electrochemical measurement, SEM and EDX analyses were carried out to examine the corrosion resistance, surface morphology and elemental compositions, respectively.
