电化学阻抗谱(Electrochemical Impedance Spectroscopy,EIS)是用于研究燃料电池电性能的一种重要手段,因其包含了大量的电池极化阻力等方面的信息.通过对电化学阻抗谱的分析可以得到电池的欧姆极化电阻、电化学极化电阻和浓差极化电阻等数据.分析了固体氧化物燃料电池常见的各种形状的交流阻抗谱,给出了各自的等效电路,并通过对等效电路的拟合求得了电池的极化电阻.与文献中普遍采用的直接读图法相比,拟合法得到的电池极化电阻数据更准确、更合理. |

Since a great deal of polarization resistance information of fuel cells is included in electrochemical impedance spectroscopy (EIS), it is an important method to characterize the performance of fuel cells. By analyzing EIS of fuel cells, all kinds of polarization resistances, such as ohmic, electrochemical and concentration polarization resistance, can be achieved. In the paper, various EIS of SOFC (Solid Oxide Fuel Cell) with typical shapes was analyzed and its equivalent circuit was presented, on which basis the polarization resistances of SOFC were calculated by fitting experiments data with complex impedance expressions. Compared with finding results just directly reading EIS curves, the results derived by this method are more rational and accurate. |
