![عکس صفحه اول مقاله: Corrosion behavior of three bipolar plate materials in simulated SPE water electrolysis environment Corrosion behavior of three bipolar plate materials in simulated SPE water electrolysis environment](/preview/png/1271039.png)
The corrosion behavior of titanium (TA2), boron-doped diamond (BDD) coated titanium and mixed metal oxide (MMO) coated titanium were studied using electrochemical impedance spectrum (EIS) in simulated solid polymer electrolyte (SPE) water electrolyte conditions at 80 °C. At imposed anodic potential, after about 240 h electrolysis, the bigger capacitance and reaction resistance values were observed for MMO coated titanium material, which demonstrated that MMO coated titanium has more corrosion-resistance performance. SEM photos showed that ten days electrolysis don't do much harm to MMO coated titanium material in simulated SPE water electrolysis environment.
► Titanium and coatings on titanium as bipolar plates.
► Evaluating bipolar plates performance using in-situ EIS when electrolyzing.
► MMO coated TA2 material is a best candidate.
