摘要：
The electrokinetics at the H-2 - Pd/SrCe0.95Yb0.05O3-alpha, interphase are presented. Current-overpotential (I-eta) curves were obtained at 400-700 degreesC and at hydrogen partial pressures from 1 kPa to 100 kPa, using a three electrode single chamber cell. The present data were assumed to be free of mass transfer effects. The anodic and cathodic charge transfer coefficients as well as the exchange current density were calculated from the experimental results by using the Butler-Volmer equation. The high and low field approximations were used to simplify the analysis.
