INFLUENCE OF POLISHING SOLUTION ON ELECTROCHEMICAL BEHAVIOR OF 304SS IN A SIMULATED PEMFC ANODE ENVIRONMENT
|
Abstract:
304 stainless steel was chemically polished with solutions such as citric acid,nitric acid,hydrogen peroxide and ferric nitrate respectively,of which the corrosion performance was then studied in a simulated PEMFC anode environment by electrochemical means.The results indicated that the corrosion current density of the polished steel was decreased one order of magnitude.The optimal concentration of the polishing solutions was 1%,60%,10% and 1% for the above polishing solutions respectively.The corrosion cur...
