“…BCZY is an oxide that can be synthesized by conventional sintering methods, with pre-defined and controlled proportions of its constituent chemical elements, with or without selective additives. The material has high chemical and structural stability and excellent electrical properties, with potential application as an electrolyte in solid-state fuel cells [84][85][86]. Most recently, Lu et al [87] reported a novel perovskite oxide (SrFe 0.3 TiO 3 ) with high conductivity and structural stabilities (at a working temperature range of 420-520 • C) for fuel cell applications.…”

Proton conductors are ceramic materials with a crystalline or amorphous structure, which allow the passage of an electrical current through them exclusively by the movement of protons: H+. Recent developments in proton-conducting ceramics present considerable promise for obtaining economic and sustainable energy conversion and storage devices, electrolysis cells, gas purification, and sensing applications. So, proton-conducting ceramics that combine sensitivity, stability, and the ability to operate at low temperatures are particularly attractive. In this article, the authors start by presenting a brief historical resume of proton conductors and by exploring their properties, such as structure and microstructure, and their correlation with conductivity. A perspective regarding applications of these materials on low-temperature energy-related devices, electrochemical and moisture sensors, is presented. Finally, the authors’ efforts on the usage of a proton-conducting ceramic, polyantimonic acid (PAA), to develop humidity sensors, are looked into.

“…18,19 The suppression of carbon deposition was also observed with Ni−Cu anodes, inhibiting anode deformation in methane-fueled protonic ceramic fuel cells. 20 Carbonate-superstructured solid fuel cells (CSSFCs), which possess ultrahigh conductivity of oxygen ions, are a new type of fuel cell with high efficiency, low cost, easy fabrication, high flexibility of fuels, and relatively low operating temperatures (∼500 °C). 21 Furthermore, the promoting effect of Ni−Cu anodes on inhibiting carbon deposition in SOFCs prompted us to explore the Ni−Cu alloy as an efficient anode for CSSFCs in this work.…”

“…Kim et al have examined Ni–Cu alloys with various compositions as anodes for the direct oxidation of methane in SOFCs at 800 °C, revealing a substantial reduction in coke formation on Ni–Cu alloys compared to pure Ni . Ni–Cu cermet anodes showed the enhanced resistance to carbon formation due to reduced adsorption energy of carbon for other hydrocarbon fuels. , The suppression of carbon deposition was also observed with Ni–Cu anodes, inhibiting anode deformation in methane-fueled protonic ceramic fuel cells …”

Unusual Promoting Effect of Ni–Cu Alloy Formation on Carbon Deposition in Carbonate-Superstructured Solid Fuel Cell with Methane Fuel

Copper is usually exploited to modify nickel-based anodes for solid oxide fuel cells for inhibiting coke formation due to its low cost, higher electronic conductivity, and inert property to carbon formation. Herein, however, it was found that the formation of a Ni–Cu alloy promoted coke formation in carbonate-superstructured solid fuel cells (CSSFCs). Namely, a Ni–Cu alloy anode suffered remarkable carbon deposition that is approximately 2 orders of magnitude greater than that in either a Ni–Cu bimetallic anode or a pure Ni anode in a CSSFC with methane fuel. The Ni–Cu alloy anodes exhibit expanded lattice parameters and surface enrichment of copper, balancing the methane decomposition and carbon diffusion processes and leading to the formation of carbon filaments, thereby diminishing both the peak power densities and the overall stability of the CSSFC.
