Proton Conductivity: Materials and Applications
TL;DR: In this paper, a review of the proton conductivity in materials and the elements of proton conduction mechanisms are discussed with a special emphasis on proton chemistry, including structural reorganization and diffusional motion of extended moieties.
Journal ArticleDOI
Solid acid proton conductors: from laboratory curiosities to fuel cell electrolytes
TL;DR: The result indicates that enhancing power output beyond the present levels will require improving cathode properties rather than further lowering the electrolyte thickness, and a discussion of the entropy of the superprotonic transition and the implications for proton transport is presented.
Journal ArticleDOI
Protonic conduction of CsH2PO4 and its composite with silica in dry and humid atmospheres
TL;DR: In this paper, the conductivity of polycrystalline CsH2PO4/silica composite was measured in the temperature range from 150 to 250 °C under a humid condition.
Journal ArticleDOI
High-Temperature Behavior of CsH2PO4 under Both Ambient and High Pressure Conditions
TL;DR: In this article, the high-temperature behavior of polycrystalline poly(H) poly(PO) was examined under both ambient and high pressure (1.0 ± 0.2 GPa) conditions.
Journal ArticleDOI
Hidden nature of the high-temperature phase transitions in crystals of KH2PO4-TYPE : Is it a physical change ?
TL;DR: In this article, it is suggested that the nomenclature high-temperature phase transition (HTPT) around T p should be replaced by that onset of partial polymerization at reaction sites distributed on the surface of solids.

Crystal structure and ferroelectricity of cesium dihydrogen phosphate CsH2PO4
Yoshiaki Uesu,Jinzo Kobayashi +1 more
TL;DR: In this article, structural and dielectric studies have been performed on CsH2PO4 for scrutinizing the validity of the previously reported structure and it is found that the symmetry in the paraelectric state is not orthorhombic as previously assumed but monoclinic with the space group of C.

Frequency dielectric dispersion in the ferroelectric and superionic phases of CsH2PO4
TL;DR: In this paper, the complex admittance was measured for CsH2PO4 in the frequency range from 30 Hz to 60 MHz and in the temperature range 90-550 K. The domain wall relaxation time was found to decrease anomalously when approaching to Tc.
Journal ArticleDOI
Dielectric properties of CsH2PO4 and CsD2PO4
TL;DR: In this article, the authors show that orthorhombic CsH 2 PO 4 undergoes a ferroelectric transition at T c = −119.5° C, whereas the ferroelectric transition temperature in isomorphous CsD 2 PO4 is Tc = −5.55° C.

High-pressure phase relations of RbH2PO4, CsH2PO4, and KD2PO4
TL;DR: The phase diagrams of RbH2PO4 (RDP), CsH2P4 (CDP), and KD2PO 4 (DKDP) have been determined to ∼40 kbar as mentioned in this paper.

New model of the bond diffractometer for precise determination of lattice parameters and thermal expansion of single crystals
TL;DR: In this article, a new model of diffractometer for very precise measurements (1 ppm accuracy) of lattice parameters and thermal expansion is presented, with special attention paid to the temperature control and stability in a wide range from liquid nitrogen up to 800 K.
