“…Currently, the most studied microtubular cells are the anode-supported ones, as this configuration allows for the reduction of the ohmic losses [39,[110][111][112][117][118][119]. The supporting microtubes are usually made by phase inversion method, which has the flexibility in control and tailoring of the microstructure.…”

“…The microtubular SOFCs have a great potential for portable applications due to fast start-up, small size, and high electrochemical characteristics reported in multiple studies (see e.g. [112][113][114][115][116][117][118][119]). However, the degradation of the cells during the long-term operation remains a weak point.…”

Solid oxide fuel cells (SOFCs) are electrochemical systems converting the energy released during fuel oxidation into electrical energy. SOFCs are considered as a promising clean energy technology due to the high efficiency of fuel-to-power conversion and environmental friendliness. The potential applications of SOFCs extend from stationary power generation units for industrial and household facilities to auxiliary power units in vehicles and portable power sources. One of the main elements of SOFCs is a solid oxide electrolyte possessing ionic conductivity at high temperatures (above 700 °C). The main challenge in the SOFC commercialization is related to their high operating temperature, which entails materials degradation, short life-time, long start-up and shut-down times, and high cost. One of the most effective ways to reduce the SOFC operating temperature is to minimize the electrolyte thickness. In this regard, fabrication of SOFCs with a thin film electrolyte has been attracting high research activity over the past few decades. Different fabrication techniques were reported to be applicable for manufacturing thin film SOFCs, and the fuel cell performance was found to be highly dependent on the appropriate selection of materials and processing technologies. The present review is focused on state-of-the-art fabrication technologies of the thin film SOFCs. A brief survey of configurations and geometries of the thin film SOFCs and methods of deposition of solid-oxide films is given. Special attention is focused on the electrical generation performance of the thin film SOFCs.

“…The single tubular cell yielded maximum power densities (MPDs) of 375, 281, 218, and 164 mW cm −2 at 650, 600, 550, and 500 °C, respectively. These MPDs are comparable with reported results on tubular PCFCs fabricated by the conventional methods, for example, extrusion (312 mW cm −2 with an effective area of 2.07 cm 2 at 600 °C), 15 slip casting (170 mW cm −2 with an effective area of 1.79 cm 2 at 600 °C), 11 and phase inversion (260 mW cm −2 with an effective area of 0.65 cm 2 at 600 °C) 24 methods. Although some single tubular cells showed slightly higher MPDs, their effective areas were below 2.5 cm 2 .…”

Protonic ceramic fuel cells (PCFCs) are clean and efficient power generation devices operating at intermediate temperatures. However, manufacturing difficulties have limited their commercialization, especially for promising tubular PCFCs. Herein, we report a cost-effective 3D printing technique for manufacturing large-area tubular PCFCs (e.g., 15.7 cm2), featured with the use of commercial raw materials, a small amount of binder, and a CO2 laser for rapid in situ drying. The technical advantages enable low-cost material preparation and efficient achievement of exemplary shape/dimension-controlled uniform microstructures in porous anode support, dense electrolyte, and porous cathode. The 3D-printed tubular PCFC (∼12.5 cm2) exhibits a power output of 2.45 W at 650 °C. Meanwhile, the long-term stability is confirmed during 200 h of operation. This novel 3D printing offers great potential to advance PCFCs from the laboratory to larger scales for realistic applications.

One of the main bottlenecks that limit the performance of reversible protonic ceramic electrochemical cells (R‐PCECs) is the sluggish kinetics of the oxygen reduction and evolution reactions (ORR and OER). Here, the significantly enhanced ORR and OER kinetics and stability of a conventional La0.6Sr0.4Co0.2Fe0.8O3–δ (LSCF) air electrode by an efficient catalyst coating of barium cobaltite (BCO) is reported. The polarization resistance of a BCO‐coated LSCF air electrode at 600 °C is 0.16 Ω cm2, about 30% of that of the bare LSCF air electrode under the same conditions. Further, an R‐PCEC with the BCO‐coated LSCF air electrode shows exceptional performance in both fuel cell (peak power density of 1.16 W cm−2 at 600 °C) and electrolysis (current density of 1.80 A cm−2 at 600 °C at 1.3 V) modes. The performance enhancement is attributed mainly to the facilitated rate of oxygen surface exchange.
