“…The electrode ink formula consisted of the following chemicals and mass percentages: 34.5 % SMMO, 9.5 % α‐terpineol, 54.0 % 2‐butanol, 0.2 % ethyl cellulose 300, 0.6 % disperbyk 111, 0.4 % polyalkyl glycol, 0.4 % polyvinyl butyral, and 0.4 % butyl benzyl phthalate. For information about aerosol printing parameters, refer to Sukeshini et al . This SMMO working electrode was then sintered at 1300 °C for 5 h. A platinum counter electrode with dimensions of 4 mm×8 mm×200 nm was sputtered 2 mm away from the SMMO working electrode.…”

Limitations of current solid oxide fuel cell anode materials have spurred the exploration of alternative materials. Mixed ionic and electronic conducting anode materials have the potential to overcome these limitations. The mixed ionic and electronic conducting material explored in this work is Sr2MgMoO6 (SMMO). X‐ray absorption spectroscopy in conjunction with an in situ assembly was used to study the fundamental redox chemistry of SMMO at 800 °C. The X‐ray absorption spectra for the Mo K‐edge exhibited changes in the reduced and oxidized bulk SMMO samples, as evident in a shift in the Mo binding energies and in the formation of oxide vacancies. However, in situ measurements of the working devices revealed that the Mo oxidation state remained unchanged under various cell polarizations. These findings demonstrate that SMMO, as a solid oxide fuel cell anode, has the potential to provide adequate electron conduction through multivalent Mo sites and to provide fuel tolerance through oxide vacancies built into its crystal structure.

“…Sukeshini et al [95][96][97] published a series of papers investigating the deposition of a yttria-stabilised zirconia (YSZ) electrolyte, a strontium-doped lanthanum manganate (LSM) cathode and a YSZ/LSM composite interlayer for use in solid oxide fuel cells (SOFCs). The interlayer material was facilitated by a dual atomisation configuration that combined two aerosol streams prior to deposition.…”

Aerosol Jet Printing (AJP) is an emerging contactless direct write approach aimed at the production of fine features on a wide range of substrates. Originally developed for the manufacture of electronic circuitry, the technology has been explored for a range of applications, including, active and passive electronic components, actuators, sensors, as well as a variety of selective chemical and biological responses. Freeform deposition, coupled with a relatively large stand-off distance, is enabling researchers to produce devices with increased geometric complexity compared to conventional manufacturing or more commonly used direct write approaches. Wide material compatibility, high resolution and independence of orientation have provided novelty in a number of applications when AJP is conducted as a digitally driven approach for integrated manufacture. This overview of the technology will summarise the underlying principles of AJP, review applications of the technology and discuss the hurdles to more widespread industry adoption. Finally, this paper will hypothesise where gains may be realised through this assistive manufacturing process.

“…In parallel with attempts to use inkjet printing to decrease the electrolyte's contribution to total cell resistance are attempts to use inkjet and aerosol jet printing to vary the composition and structure of the solid oxide fuel cell anode and cathode functional layers. Functional grading may facilitate post‐printing processing by decreasing thermal stresses associated with co‐sintering electrolyte and anode layers, and also increase performance by optimizing the mix of ion and electron conducting materials within the anode and cathode functional layers . The use of inkjet printing to simply vary anode interlayer composition from NiO/YSZ to NiO/CuO/YSZ showed the distinct advantage of the NiO/CuO/YSZ layers in terms of both power output and resistance to poisoning with solid carbon fuel .…”

Functionally graded aerosol jet printed NiO/YSZ materials show improved performance over ungraded aerosol jet printed materials . A particularly effective version of functional grading was demonstrated through inkjet printing of a LCSF‐GDC cathode intermediate layer .…”

“…Finally, solvent vapor pressure must be tuned, so that the atomizer nozzle does not clog and so that fluid does not evaporate prior to delivery on the substrate. This is generally thought to require solvents with boiling points above ≈180 °C, although lower boiling point solvents have been used for aerosol jet printing, as have binary mixtures of high and low boiling point solvents . As in the case of inkjet printing, once jettable inks have been formulated, ink mixing or materials grading can be performed through co‐deposition of two or more separate materials streams.…”

Inkjet and aerosol jet printing have recently emerged as promising fabrication techniques for a broad range of devices for electrochemical energy conversion and storagebatteries, fuel cells, and supercapacitors. If fully realized, these printing techniques may enable device performance advantages accruing from precise micron scale patterning, thin layer deposition, and materials grading. Printing may also allow scalable, low materials waste manufacturing, and conformal integration of power elements into structural elements. This article reviews the fundamental capabilities of inkjet and aerosol jet printing relevant to electrochemical devices, surveys current literature, and presents future challenges which must be tackled to achieve high performance, printed electrochemical energy storage, and conversion devices.
