Development of Plasma-Sprayed Molybdenum Carbide-Based Anode Layers with Various Metal Oxides for SOFC

“…However, the power densities obtained by Heo et al [9][10] were substantially lower (in 10's of mW/cm 2 ) than those reported for other SOFCs (in 100's of mW/cm 2 [5][6]). This was attributed to large thickness (~1000 µm) of the electrolyte (i.e.…”

“…Reducing the operating temperature to intermediate range can lower the cost but also reduce the reaction rate [3]. Some of the recent articles [4][5][6][7][8] summarize most of the known SOFC materials (electrodes, electrolytes, interconnects) and their manufacturing alternatives, relevant to modern requirements. However, the scope of this work is to present a development of air plasma sprayed (APS) new anode materials for SOFC systems.…”

“…However, these techniques face several problems [5][6], which include: (a) use of multiple separate instruments, (b) increased capital cost due to high temperature firing, thermal expansion mismatch strain and cracking during high-temperature firing steps, and (c) inter-reaction between adjacent cell layers at high-temperature firing steps and d) limitation of hightemperature sintering of anode and metallic interconnect materials. Heo et al [9][10] recently developed a new efficient type of fuel cell that runs directly on hydrocarbons.…”

Recent progress in solid oxide and lithium ion conducting electrolytes research

“…Table 1 lists the potential oxide electrolytes and comments on their technological problems with regard to their application in Fig. 1 Regime of electrical conductivity of solid electrolytes at room temperature as shown by the broken lines and compared with the electrical conductivities of typical metals, semiconductors, and insulators fuel cells [9][10][11][12][13][14][17][18][19][20][21][22][23][24][25]. Figure 2 shows the Arrhenius plots for the oxide ion conductivities of selected metal oxides [13].…”

La1-xSrxCo1-yFeyO3-d (LSCF) Composite as Durable Cathode Materials for Intermediate-Low Temperature Solid Oxide Fuel Cell: Research Review

“…Prestasi bahan katod sangat bergantung kepada saiz ira, mikrostruktur, proses pembentukan atau pengendapan dan suhu (Wincewicz & Cooper 2005 Pendekatan lain yang dilakukan oleh penyelidik untuk meningkatkan prestasi keseluruhan SFOP adalah melalui penggunaan katod perovskit berstruktur nano (Serra et al 2006). Kajian yang dibuat oleh Barque et al (2008) dengan menggunakan serbuk katod bersaiz 130-180 nm, membuktikan bahawa prestasi katod dan rintangan luas tentunya sangat bergantung kepada mikrostruktur dan komposisi.…”
