应用空心阴极离子镀工艺在质子交换膜燃料电池用钛双极板试样表面上沉积了总厚度约3μm的 Cr/TiN／Ti纳米晶复合镀膜,测定了纳米晶复合镀膜钛板和裸钛板的接触电阻,采用极化曲线评价其在分别通入O_2和H_2的60℃,0.05mol／LH_2SO_4+2mg/LNaF溶液中的耐蚀性能,结果表明,镀膜钛板的接触电阻明显低于裸钛板,在1000N／cm~2的压力下镀膜试样的接触电阻值约为12mΩ.Cm~2;在通入H_2的情况下,Cr／TiN/Ti纳米晶复合镀膜钛板的维钝电流密度与裸钛板相比降低了一个数量级,耐腐蚀性能得到明显改善, |

Cr/TiN/Ti nanocrystalline composite films of about 3 μm were deposited on titanium bipolar plates for proton exchange membrane fuel cell (PEMFC)by hollow cathode deposition (HCD)ion plating.The electrical contact resistance of Ti plate with and without the nanocrystalline films was tested respectively,and their electrochemical corrosion performance was evaluated in 0.05 mol/L H2SO_4+2 mg/L NaF solutions bubbled with H_2 or O_2 at 60 ℃ by means of polarization measurements.The results show that the contact resistance of the coated Ti plate was obviously lower than that of bare Ti plate,with about 12 mΩ·cm~2 under a compressive presure 1000 N/cm~2.The passivation current density of the coated Ti plate was one order of magnitude smaller than that of the bare Ti plate under the condition of charging hydrogen,suggesting that the corrosion resistance of titanium bipolar plate is greatly improved by the deposition of Cr/TiN/Ti nanocrystalline composite films. |
