Ion transport in crystalline fast ionic conductors is a complex physical phenomenon. Certain
ionic species (eg, Ag+, Cu+, Li+, F–, O2–, H+) in a solid crystalline framework can move as …

Solid-state proton and hydride anion conductors are an important family of materials as
electrolytes for solid state electrochemical cells such as fuel cells, batteries, sensors, and …

In this review article, new systems being investigated for application in solid oxide fuel cells
are discussed. For the electrode materials, materials with the perovskite or related structures …

A simple hydrothermal method has been developed for the systematic synthesis of
lanthanide orthophosphate crystals with different crystalline phases and morphologies. It …

For the development of proton-based electrolytes, high proton conductivity at intermediate
temperatures (300–600° C) is crucial, but the available materials have been confined to a …

Proton conductors are promising materials for clean energy, but most available materials
exhibit sufficient conductivity only when chemically substituted to create oxygen vacancies …

Proton conductors have found diverse applications, such as electrolytes in proton ceramic
fuel cells, which require high ionic conductivity at low temperatures and high chemical …

This book proposes a wide overview of the research and development of proton-conducting
solid oxide materials. It is the first to approach the topic on proton-conducting ceramics and …

The gradual change in the crystal structure of the high temperature proton conductor
LaNbO4 through a second order phase transition and its relation to the activation enthalpy of …

Electrical conduction in rare earth orthophosphates, LnPO4 (Ln= La, Pr, Nd and Sm), with
the monazite structure (P21/n) was investigated by using conductivity measurements at 500 …
