Рубрики: ХИМИЧЕСКИЕ НАУКИ Кл.слова (ненормированные): ELECTRODE SYSTEM -- POLARISATION RESISTANCE -- O2, Au/O2- -- H2-H2O, Au/O2- Аннотация: 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 (3-22)x10-4 S·cm-1 dependent on the electrode history in pure oxygen at 977 °C and 2x10-6 S·cm-1 at 977 °C in “pure” hydrogen (PO2=10-20 atm at 1001 °C). The results are compared with previous data obtained for platinum electrodes. \\\\Cserver\\dist\\НБО\\Cтатьи БД ИВТЭ\\Ionics\\2003, V. 9, № 1-2, С. 140-150.pdf |
