  • In order to evaluate the corrosion resistance of metal bipolar plate in direct ethanol fuel cell (DEFC) environment, a solution of 0.05 mol/L H2SO4 +x mol/L CH3CH2OH (x=0,1,5,10,13) was used to simulate DEFC anode operating environment. In the environment, the surface morphology of 304 stainless steel (304SS) was characterized, and the electrochemical tests were carried out for polarization and constant current time-current density. The results showed that ethanol had not much effect on 304SS corrosion potential. Ethanol played a role in slowing the corrosion rate of 304SS in 0.05 mol/L H2SO4 solution. 304SS had a high stability in DEFC operating environment with high ethanol concentration.
