摘要：

Gold electrodes with known contact geometries were studied using impedance spectroscopy. From these data it was possible to determine the specific polarisation conductivity per unit length of three-phase boundary (TPB). The values were found to be (3divided by22)x10(-4) S.cm(-1) dependent on the electrode history in pure oxygen at 977 degreesC and 2x10(-6) S.cm(-1) at 977 degreesC in "pure" hydrogen (P-O2 = 10(-20) atm at 1001 degreesC). The results are compared with previous data obtained for platinum electrodes.
