提出了一种测试方法，以获得正确的极化曲线的PEFC单电池与参比电极，这在原则上应具有相同的阳极极化曲线的H2/O2和H2/空气。测量的阳极极化曲线通常与电流密度呈线性关系，但不是欧姆性的。阴极和参比电极之间的漏电流引起阳极极化曲线上的电压偏移。为了获得欧姆阳极极化，应将测量的阳极极化曲线垂直向上移动，使其与基点重叠。与参比电极相邻的电极边缘的配置对阳极和阴极电势产生显著影响。比另一电极更靠近参比电极0.5mm的电极的极化不包括膜的欧姆损失。相反，另一个电极的极化包括膜的欧姆损失。© 2010 Wiley Periodicals，Inc.

A test method is proposed for obtaining correct polarization curves of PEFC single cells with reference electrodes, which in principle should have identical anode polarization curves for both H2/O2 and H2/Air. Measured anode polarization curves are usually linear to the current density but not ohmic. Leak current between cathode and reference electrode causes voltage shift on the anode polarization curve. In order to obtain the ohmic anode polarization, the measured anode polarization curve should be moved vertically up to overlap with the base point. Configuration of the electrode edge adjacent to the reference electrode gives a significant effect on the anode and cathode potential. Polarization of an electrode which is 0.5 mm nearer to the reference electrode than the other electrode does not include the ohmic loss of the membrane. Instead, polarization of the other electrode includes the ohmic loss of the membrane. © 2010 Wiley Periodicals, Inc.
