摘要：

The protonic conductivities of SrZr0.95M0.05O3 doped with four acceptor ions (M3+ = Y3+, Sc3+. Yb3+, Er3+) have been studied in the single crystal form. The protonic conductivity is found in four acceptor ions, indicating that protons migrate by hopping from site to site. The Yb-doped crystal has the lowest activation energy and the highest conductivity amongst the four acceptor ions. This is considered to be due to the difference in strength of the O-H bond with different acceptor doping.
