“…Materials that exhibit high protonic conductivity in the solid state and at elevated temperatures (T > 500 ~ are very useful in heterogeneous catalysis because they can operate at temperatures in which industrially important hydro-and dehydrogenation reactions take place [ 1,2]. Such proton conducting solid electrolytes are rare earth oxides or perovskites (SrZrO 3 and SrCeO3) doped by a B-side acceptor, such as yb3+ or y3+.…”

Abstract. The eleclxokinetics at the H 2 -Pd/SrCeo.95Ybo.0503_ct interphase are presented, Currentoverpotential (I-'q) curves were obtained at 400-700 ~ 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.

“…At the beginning of the 1980s, Professor H. Iwahara in Japan discovered that perovskite-type oxides, MCel_xLxO 3 (M = Ba or Sr, L = Yb or Nd), exhibit proton conductivity in hydrogen or moist air at temperatures above 700 ~ [10][11][12]. The attempts of using those materials as electrolyte to construct SOFCs also achieved exciting results.…”

Abstract. The paper describes the features of fuel cells using proton conductors as electrolyte.Comments on the properties of some intermediate and high temperature proton conductors and their applications for fuel cells are given. Finally, further research areas including the search for new proton conductors and new electrode materials compatible to the electrolytes as well as the development of preparation techniques are proposed.

“…Only recently, however, materials that exhibit protonic (H § conductivity in the solid state have been discovered and introduced into catalytic research [2]. Solid state proton conductors are particularly useful in catalysis because they can operate at temperatures in which many industrial hydro-and dehydrogenation reactions take place [3].…”
