“…Capital cost is a function of several factors, such as production volume and scale of the units, and material supply chain. One might expect a drastic reduction in capital costs with improved cell designs such as microtubular cells (Lei et al, 2017;Chen et al, 2019;Monzón and Laguna-Bercero, 2019), advent of new manufacturing processes such as 3D printing (Huang et al, 2017;Wei et al, 2019), and advanced automation which can be implied if the technology gains market acceptance. The challenges associated with materials are more fundamental in nature, and the degradation mechanism in SOECs is not yet well understood.…”

Environmental issues related to global warming are constantly pushing the fossil fuelbased energy sector toward an efficient and economically viable utilization of renewable energy. However, challenges related to renewable energy call for alternative routes of its conversion to fuels and chemicals by an emerging Power-to-X approach. Methane is one such high-valued fuel that can be produced through renewables-powered electrolytic routes. Such routes employ alkaline electrolyzers, proton exchange membrane electrolyzers, and solid oxide electrolyzers, commonly known as solid oxide electrolysis cells (SOECs). SOECs have the potential to utilize the waste heat generated from exothermic methanation reactions to reduce the expensive electrical energy input required for electrolysis. A further advantage of an SOEC lies in its capacity to coelectrolyze both steam and carbon dioxide as opposed to only water, and this inherent capability of an SOEC can be harnessed for in situ synthesis of methane within a single reactor. However, the concept of in situ methanation in SOECs is still at a nascent stage and requires significant advancements in SOEC materials, particularly in developing a cathode electrocatalyst that demonstrates activity toward both steam electrolysis and methanation reactions. Equally important is the appropriate reactor design along with optimization of cell operating conditions (temperature, pressure, and applied potential). This review elucidates those developments along with research and

“…16,17 In this direction, Ruiz-Morales et al 18 lately reviewed the use of 3D printing for energy applications suggesting the interest of stereolithography (SLA) printing for developing high aspect ratio highly performing SOFCs. According to Ruiz-Morales, the different works devoted to the development of SOFCs by 3D printing were focused on the fabrication of planar cells [19][20][21][22][23][24][25][26][27][28][29][30][31] with the only exception of the one recently published by the authors 32 in which honeycomb structures were used to improve the mechanical stability of 3D printed YSZ membranes.…”

“…An increase in the concentration of Disperbyk-111 caused a decrease in viscosity and 3 wt% of this dispersant provided a 40 vol% ceramic slurry viscosity suitable for the suitable for DLP additive manufacturing (2.3 Pa.s at 30 s -1 ). The shear-thinning behavior presented by these suspensions is characteristic of VP ceramic slurries 21,42,43,47,[49][50][51][52][53] . Such behavior is desirable in VP 1,54,55 because it avoids sedimentation of the suspension in a stationary state, and adequate flow when a shear rate is applied to the slurry 32 .…”

Vat photopolymerization (VP) stands out among ceramic additive manufacturing processes for its ability to print sub-100 micrometer complex features. One of the main challenges of this process is the preparation of a homogeneous and stable ceramic slurry with a high solid load and low viscosity. In this work, different dispersants and resins were tested, aiming to provide a solvent-free slurry suitable for DLP additive manufacturing. Disperbyk-111 and PEGDA 250 stood out in the tests, providing a 40 vol% ceramic slurry with no noticeable sedimentation and viscosity of 2.3 Pa.s at 30 s -1 despite the relatively high specific surface area (15 m 2 /g) of the 3Y-TZP powder used compared to powders usually used for VP slurries. The adsorption of Disperbyk-111 on ceramic particles surface was investigated by FTIR. Finally, ceramic bodies were 3D printed, debound and sintered at 1500 ºC for 2 h, confirming the ability to manufacture detailed dense ceramic parts.
