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. Держатели документа: Центральная научная библиотека УрО РАН Доп.точки доступа: Primdahl, S.; Mogensen, M.
