“…[ 9,10 ] In the past decade, tremendous efforts have been made in the fabrication of thin‐film proton‐conducting electrolytes and significant progress has been gained. [ 11–14 ] For example, spray casting, spin coating, screen printing, and sintering aid have turned out to be effective methods in preparing high‐quality proton‐conducting electrolytes with mass production capabilities. It suggests that the development of efficient electrode materials is of particular importance for realizing high power outputs of PCFCs at ILT range.…”

Here a new strategy is unveiled to develop superior cathodes for protonic ceramic fuel cells (PCFCs) by the formation of Ruddlesden–Popper (RP)‐single perovskite (SP) nanocomposites. Materials with the nominal compositions of LaSrxCo1.5Fe1.5O10−δ (LSCFx, x = 2.0, 2.5, 2.6, 2.7, 2.8, and 3.0) are designed specifically. RP‐SP nanocomposites (x = 2.5, 2.6, 2.7, and 2.8), SP oxide (x = 2.0), and RP oxide (x = 3.0) are obtained through a facile one‐pot synthesis. A synergy is created between RP and SP in the nanocomposites, resulting in more favorable oxygen reduction activity compared to pure RP and SP oxides. More importantly, such synergy effectively enhances the proton conductivity of nanocomposites, consequently significantly improving the cathodic performance of PCFCs. Specifically, the area‐specific resistance of LSCF2.7 is only 40% of LSCF2.0 on BaZr0.1Ce0.7Y0.2O3−δ (BZCY172) electrolyte at 600 °C. Additionally, such synergy brings about a reduced thermal expansion coefficient of the nanocomposite, making it better compatible with BZCY172 electrolyte. Therefore, an anode‐supported PCFC with LSCF2.7 cathode and BZCY172 electrolyte brings an attractive peak power output of 391 mW cm−2 and excellent durability at 600 °C.

“…[70][71][72] For instance, NiO-BCZY anode was spin-coated on BCZY electrolyte at 3000 rpm for 50 s and the resultant anode was highly dense and free from any cracks. 71 Symmetrical cells of CuO-CGO/CGO/CuO-CGO were also prepared by spin-coating of CuO-CGO slurry on flat surfaces [104][105][106] of CGO pellets. 73 The cells were initially baked in a microwave oven at 80 W followed by sintering at 700 C for 3 h. The resultant anode had sufficient porosity with a spongy microstructure.…”

The primary components of SOFCs are the anode, cathode, and the electrolyte. Anode is critical in achieving the effective electrochemical oxidation of fuel; thus, its performance can be improved using homogenous powder synthesized through an appropriate method. Various synthesis methods, including solidstate reaction and wet chemical methods have been used to synthesize anode materials. However, each technique has several advantages and disadvantages.Given that anode is a porous electrode, few criteria, such as high conductivity, tolerance towards carbon deposition, chemical stability, and thermal stability, must be fulfilled. Researchers also modified the existing synthesis method to improve the performance of the anode. In addition, various anode fabrication techniques including physical and colloidal deposition techniques are briefly discussed to understand their effect on the performance of the deposited layers.The aim of this review is to discuss the various anode synthesis and deposition techniques and their influence on the properties and performance of SOFCs.

“…Solid Oxide Fuel Cell (SOFC) adalah pembangkit listrik yang sangat potensial dikarenakan memiliki efisiensi yang tinggi, fleksibilitas bahan bakar, penggunaan katalis yang murah, dan emisi pengotor yang rendah, yang mana kategori tersebut sangat penting untuk sistem mesin konversi energi masa depan [1][2]. SOFC konvensional menggunakan prinsip transfer ion oksigen (O 2--SOFC) dan beroperasi pada kisaran temperatur 800-1000 °C.…”

“…Dibandingkan dengan SOFC konvensional, pengembangan ini memungkinkan untuk penggunaan material yang relatif lebih murah untuk interkoneksi, kontrol sintering elektrode yang lebih baik, interaksi elektrode dan elektrolit pun semakin bagus, dengan demikian bisa memperpanjang masa operasional SOFC. H + -SOFC juga memiliki konduktivitas proton yang tinggi, serta aktivasi energi yang rendah [2][3].…”

“…Struktur anode supported untuk SOFC diterima di dunia karena kemudahan penyalaan, sifat elektrokatalitik yang lebih baik, dan efisiensi yang lebih baik [7]. Di antara semua aditif sintering oksida logam, nikel adalah yang paling efektif dan telah umum digunakan dalam anoda cermet O 2--SOFC atau H + -SOFC [2]. Membran komposit yang mengandung nikel dan konduktor proton padat BaCe 0.7 Zr 0.1 Y 0.2 O 3-(BCZY) dapat digunakan sebagai pemecah hidrogen tanpa elektroda atau sirkuit elektrikal eksternal, sehingga lebih menguntungkan dibandingkan sistem konvensional [8].…”

The purpose of this study is to investigate the microstructure characteristics of the Ni1-xCux-BCZY anode and to analyze the carbon resistance by doping Cu into the Ni-BCZY anode. Ni1-xCux and BaCe0.7Zr0.1Y0.2O3-𝛿 (BCZY) powder were prepared by solid-state reaction with Ni1-xCux /BCZY = 60:40 wt%. The powder is calcined at a temperature of 700 °C, sintered at 1450 °C, and reduced by pure H2. The results of the Ni1-xCux-BCZY microstructure show an increase in the average particle size from 2.71 to 2.88 µm with increasing calcination time from 0.5 to 1.5 hours. Furthermore, the conductivity of Ni1-xCux-BCZY (x = 0.1) is lower than Ni1-xCux-BCZY (x = 0), this is associated with enhancement electron scattering, which correlatives with large metal particle obtained. The optimum conductivity of Ni1-xCux-BCZY(x=0.1) is obtained at a calcination time of 0.5 hours. Furthermore, NiCu anode can effectively increase the carbon resistance while using methane as a fuel.
