“…36−39 Furthermore, during the conventional methods (extrusion, dip coating, and phase inversion) and fused filament fabrication, a high amount of binder (e.g., mass ratios of binder/ceramics are 10−25 wt %) is usually required, which may cause severe deformation issues during the postdrying/ sintering processes. 18,27,29,30,41 In our case, the binder content (e.g., hydroxypropyl methylcellulose) in the paste is only 0.31 wt %, ensuring the feasible viscosity for printing and mitigating the deformation issues. Moreover, to further achieve good shape retainability of the anode and ensure good adhesion between printed layers without requiring high paste viscosity, a CO 2 laser was used for rapid in situ drying of the printed green body after printing each layer of the anode support.…”

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.

“…Planar and tubular SOFCs and SOECs are conventionally used for different applications. While the planar cells are attractive for stationary application due to their long start up time, the tubular cells are more beneficial for mobile application due to their short start-up time [7]. The other advantageous of tubular SOFCs and SOECs are mechanical strength, high volumetric power density, high thermal cyclic behaviour and less problematic sealing compared to the planar ones [8,9].…”

BaCe0.7Zr0.1Y0.16Zn0.04O3-δ (BCZYZ) ceramic slurry has been prepared with different solid loading and the maximum solid loading of the slurry has been predicted as 25 vol.% using the Krieger-Dougherty equation. The slurry with the maximum solid loading has been formulated and applied as an electrolyte on porous NiO/BCZYZ tubular supports by the dip-coating method. Cells sintered at 1500°C for 10h have been characterised by Scanning Electron Microscopy (SEM) analysis. The 30μ thick, very dense electrolyte layer has successfully been achieved with some closed pores.

“…To bring this potential fuel cell technology closer to commercialization, there is a need to fabricate these devices with suitable up-scalable technologies such as printing methods. Digital manufacturing has been recently introduced to fabricate ceramic fuel cells [ 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 ]. Digital manufacturing offers various advantages over conventional printing techniques such as screen printing [ 38 , 39 ] and tape casting [ 40 , 41 ].…”

“…On the contrary, conventional printing techniques restrict the shape of the cell architecture to planner and tubular designs. Several digital printing technologies, including direct inkjet printing [ 23 , 24 ], selective laser sintering [ 25 , 26 ], stereolithography [ 27 , 28 ], digital light processing [ 29 , 30 ], robocasting or extrusion (also known as direct writing) [ 31 , 32 , 33 , 34 ], a hybrid of different technologies [ 35 , 36 , 37 ] etc., have been used to fabricate the anode, electrolyte or cathode of a three-layer ceramic fuel cells. Among these technologies, extrusion-based 3D printing is one of the most promising technologies to fabricate single-layer ceramic fuel cells with the least material waste, and it is employed in this work.…”

Systematic Analysis on the Effect of Sintering Temperature for Optimized Performance of Li0.15Ni0.45Zn0.4O2-Gd0.2Ce0.8O2-Li2CO3-Na2CO3-K2CO3 Based 3D Printed Single-Layer Ceramic Fuel Cell

Single-layer ceramic fuel cells consisting of Li0.15Ni0.45Zn0.4O2, Gd0.2Ce0.8O2 and a eutectic mixture of Li2CO3, Na2CO3 and K2CO3, were fabricated through extrusion-based 3D printing. The sintering temperature of the printed cells was varied from 700 °C to 1000 °C to identify the optimal thermal treatment to maximize the cell performance. It was found that the 3D printed single-layer cell sintered at 900 °C produced the highest power density (230 mW/cm2) at 550 °C, which is quite close to the performance (240 mW/cm2) of the single-layer cell fabricated through a conventional pressing method. The best printed cell still had high ohmic (0.46 Ω·cm2) and polarization losses (0.32 Ω·cm2) based on EIS measurements conducted in an open-circuit condition. The XRD spectra showed the characteristic peaks of the crystalline structures in the composite material. HR-TEM, SEM and EDS measurements revealed the morphological information of the composite materials and the distribution of the elements, respectively. The BET surface area of the single-layer cells was found to decrease from 2.93 m2/g to 0.18 m2/g as the sintering temperature increased from 700 °C to 1000 °C. The printed cell sintered at 900 °C had a BET surface area of 0.34 m2/g. The fabrication of single-layer ceramic cells through up-scalable 3D technology could facilitate the scaling up and commercialization of this promising fuel cell technology.
