“…Modern fabrication methods for ceramic layers allow for the deposition of a gas-tight thin electrolyte layer (<20 mm) able to uniformly cover the anode surface. Good adhesion is also required in the electrolyte film deposited to the anode surface [ 30 , 31 , 32 ].…”

The development of new chemically resistant anodes for protonic ceramic fuel cells (PCFCs) is urgently required to avoid the costly deep hydrogen purification method. Ba0.95Ca0.05Ce0.9Y0.1O3−δ (5CBCY), which is more chemically resistant than BaCaCe0.9Y0.1O3−δ, was here tested as a component of a composite NiO–5CBCY anode material. A preparation slurry comprising 5CBCY, NiO, graphite, and an organic medium was tape cast, sintered and subjected to thermal treatment in 10 vol.% H2 in Ar at 700 °C. Differential thermal analysis, thermogravimetry, quadrupole mass spectrometry, X-ray diffraction analysis, scanning electron microscopy, the AC four-probe method and electrochemical impedance spectroscopy were used for the investigation. The electrical conductivity of the Ni–5CBCY in H2–Ar at 700 °C was 1.1 S/cm. In the same gas atmosphere but with an additional 5 vol.% CO2, it was slightly lower, at 0.8 S/cm. The Ni–5CBCY cermet exhibited repeatable electrical conductivity values during Ni-to-NiO oxidation cycles and NiO-to-Ni reduction in the 5CBCY matrix, making it sufficient for preliminary testing in PCFCs.

“…Understanding the mechanical properties of ionic conductors are also important from the application point of view [22,26,29,[46][47][48]. From the side of materials synthesis, we may cite for instance, the mechanically milling process which are widely used in the preparation of solid electrolytes used in batteries [46].…”

“…A short summary of recent works on elastic, plastic, and fracture properties of crystalline oxide-based Li-ion solid electrolytes is available in [26]. As noted in many studies [22,26,29,[46][47][48], the role of mechanical properties in a real battery system is multiple and complex. It extends from fundamental materials properties to assembly of devices.…”

Ionic Conductors: Effect of Temperature on Conductivity and Mechanical Properties and Their Interrelations

The ionic transport and the mechanical properties in solids are intimately related. However, few studies have been done to elucidate the background of that relation. With the objective to fill this gap and gain further understanding on the fundamental properties of ion conducting materials, we are studying systematically the mechanical properties of different materials. In the present study, after showing briefly our previous results obtained in crystalline materials, results regarding the relation between ionic conduction and mechanical properties in superionic glasses is presented. All these results indicate the intimate relation between the mechanical and ionic conduction. The results also indicate that the Grüneisen parameter and the Anderson–Grüneisen parameter of ionic conductors exhibit large temperature dependence and increase with temperature.
