| Abstract: | Two different bipolar plates were fabricated using macrocyclic disulfide oligomers and expanded graphite via in situ ring opening polymerization(ROP).Their aging behavior was investigated by means of the immersion test.The aging behavior was characterized according to the changes in property before and after the immersion test.The electrical conductivity and mechanical properties were determined using the four-probe method and three point bending method,respectively.The experimental results show that the as-made bipolar plates have good corrosion resistibility in the simulated solution of(0.01) mol/L HCl (0.01) mol/L Na_2SO_4. |
