“…Although here we have presented results regarding water electrolysis in the PCEC, similar materials can also be used for carrying out CO 2 electrolysis and related electrochemical reforming processes [59][60][61] . In detail, Ln 2 NiO 4 + δ -based nickelates exhibit excellent CO 2 -tolerance [62][63][64] , while an appropriate stability of the Ba(Ce,Zr)O 3 proton-conducting electrolytes can be achieved by increasing the Zr/Ce ratio [24,26] .…”

“…Although some operability issues of PCECs with Ln 2 NiO 4 + δbased electrodes have recently been revealed [17,[21][22][23][24] , the existing results were obtained for planar-type cells having a relatively small electrode area (not more than 0.5 cm 2 ). In pursuing the idea of improving overall performance, we hereby present the results of an experimental fabrication of a tubular-type PCEC having an enlarged effective area along with its subsequent characterisation.…”

Protonic ceramic electrolysis cells (PCECs), which permit high-temperature electrolysis of water, exhibit various advantages over conventional solid oxide electrolysis cells (SOECs), including cost-effectiveness and the potential to operate at low-/intermediate-temperature ranges with high performance and efficiency. Although many effort s have been made in recent years to improve the electrochemical characteristics of PCECs, certain challenges involved in scaling them up remain unresolved. In the present work, we present a twin approach of combining the tape-calendering method with all-Ni-based functional electrodes with the aim of fabricating a tubular-designed PCEC having an enlarged electrode area (4.6 cm 2 ). This cell, based on a 25 μm-thick BaCe 0.5 Zr 0.3 Dy 0.2 O 3-δ proton-conducting electrolyte, a nickelbased cermet and a Pr 1.95 Ba 0.05 NiO 4 + δ oxygen electrode, demonstrates a high hydrogen production rate (19 mL min -1 at 600 °C), which surpasses the majority of results reported for traditional button-or planar-type PCECs. These findings increase the scope for scaling up solid oxide electrochemical cells and maintaining their operability at reducing temperatures.

Developing an efficient and economic technique for CO 2 conversion can both eliminate the environmental effect and provide an effective solution for energy storage, therefore attracting great attention in the past decades. Proton-conducting solid oxide cells (H-SOCs) have recently emerged as a promising approach for converting CO 2 into valuable chemicals with high efficiency and good selectivity. In this review, we summarize recent progress of using H-SOCs for the reforming reaction of CH 4 and CO 2 as well as the co-electrolysis of CO 2 and H 2 O. The conversion performance, reaction mechanism, and material development are discussed in detail. Some other reactions such as CO 2 hydrogenation using H-SOC are also presented. Finally, we point out the challenges and outlooks for CO 2 conversion using H-SOCs.

“…Both of these results indicate that the studied materials exhibit the desirable stability in CO 2 -containing atmospheres. This permits the use of such materials as electrolytes for the various electrochemical and conversion processes in which CO 2 participates as a reagent or product [51][52][53][54].…”

The effective operation of protonic ceramic electrochemical cells requires the design of electrolytes having not only high ionic conductivity, but also excellent stability with respect to carbonisation. In the present work, the La-based oxides (La 1-x Ba x YbO 3-δ, 0.03 ≤ x ≤ 0.10) are proposed as a possible alternative to the convenient Ba (Ce,Zr)O 3-based electrolytes due to their high chemical stability. It was discovered that Ba-doping results in a deterioration of sintering behaviour; as a result, the relative density decreases and open porosity appears (for x = 0.10). A thorough analysis of transport properties by means of AC and DC measurement techniques enables a selection of the La 0.97 Ba 0.03 YbO 3-δ sample, which demonstrates the highest conductivity compared with those samples where x = 0.5 and 0.10. Due to its excellent densification behaviour, stability and ionic conductivity, La 0.97 Ba 0.03 YbO 3-δ can be considered as a promising proton-conducting electrolyte in the La-based family.
