Insights into Interfacial Proton Transport in Protonic Ceramic Conductors
ECS Meeting Abstracts, 2021Understanding the mechanism of proton conduction at the interface of materials enables the development of a new generation of protonic ceramic conductors at low temperatures (< 300 °C) through water absorption and proton transport on the interface.

physica status solidi (b), 1970
AbstractA comprehensive NMR study of powdered proton conductor borax provides information on one rotary mode of crystal water. This mode is fast enough to maintain the conductive chain depolarized. The proton conductivity “bottleneck” mode is a flipping mode of another water molecule in the conductive chain.

SOFC Based on Proton Conductors
ECS Transactions, 2007We have fabricated a solid oxide fuel cell (SOFC) using BaCe0.8Y0.2Ox (BCY20) proton conductor as the electrolyte. An ≈10-μm-thick dense BCY film was prepared on a porous Ni/BCY cermet (i.e., ceramic/metal composite) substrate by a dip coating process.

Polypeptide for anhydrous proton conductor
Electrochimica Acta, 2014Abstract The anhydrous proton conductor consisting of a polypeptide was prepared by the mixing of polyglutamic acid (poly(Glu)) and polyhistidine (poly(His)), which were synthesized by the polymerization of an amino acid with diphenylphosphoryl azide (DPPA). These polypeptide hybrid materials interacted between the carboxyl group of poly(Glu) and the

New inorganic proton conductors
Materials Research Bulletin, 1982High values of proton conductivity have been observed in a class of hydrated metal oxide pyrochlores, HMO/sub 3/.xH/sub 2/O (M = Sb, Nb, Ta). Two new polymorphs of HSbO/sub 3/.xH/sub 2/O have been synthesized and are also found to be good proton conductors. One polymorph has a layer structure and is derived from KSbO/sub 3/ with the ilmenite structure.

Ionic Conductors and Protonics
2017Understanding ion conduction mechanisms on the atomic scale remains a fundamental problem in many areas of science, from biological and chemical systems to many materials of high interest to science and society. In particular, the local structure and chemistry complicate the description about ionic conduction, which is still not fully understood for ...

Proton conductors and metal hydrides
Solid State Ionics, 1995Abstract Some applications for high temperature ceramic proton conductors are proposed. Included are hydrogen production and transport, measurement of hydrogen activity, hydrogen isotope separation, power production and power storage. Small scale hydrogen production based on electrolysis of moisture is envisioned for the charging of metals with ...

Unique Proton Dynamics in an Efficient MOF-Based Proton Conductor
Journal of the American Chemical Society, 2017Recently, research on metal-organic frameworks (MOFs) serving as a new type of proton conductive material has resulted in many exciting achievements. However, direct observation of a well-established proton-transfer mechanism still remains challenging in MOFs and other crystalline compounds, let alone other conductive materials.
