“…However, there are still several challenges facing the commercialization of SOFC technology. SOFC is also one kind of distributed energy that can be deployed onsite (Stationary power/ combined heat and power applications), even in urban areas, portable application and advanced clean energy solutions (1)(2)(3)(4)(5)(6)(7)(8)(9)(10). Metal-supported solid oxide fuel cells (MS-SOFCs), the supporting component for the ceramic anode, electrolyte and cathode layers of the cell is made of porous alloy substrate and is referred to as the third generation of SOFCs.…”

In this study, the large-scale mold for compression molding process is prepared and a compression load of 120 ton is applied to form a porous alloy specimen with dimension of 120×120×1.2 mm. The carbon is used as pyrolyzable filler in the period of manufacturing processes in order to produce porous interconnected networks of molybdenum (Mo)-containing nickel (Ni)-based alloy. The specimens are sintered in hydrogen at 1250°C to obtain porous alloy substrate. The flexural strength of porous alloy supporting component is measured in this work. The strength of porous alloy substrate (sintered at 1250°C) in three-point flexure at 25°C and 750°C are 188 MPa and 76.5 MPa, respectively. Metal-supported solid oxide fuel cells (MS-SOFCs) are fabricated by thermal plasma spraying technique and the anode (Ce 0.55 La 0.45 O 2-δ -NiO), electrolyte (La 0.8 Sr 0.2 Ga 0.8 Mg 0.2 O 3-δ ) and cathode (Sm 0.5 Sr 0.5 CoO 3-δ ) functional layers are deposited onto porous alloy substrate. The 10×10 cm 2 MS-SOFC with effective electrode area of 81 cm 2 shows the open circuit voltage is 1.09 V at 700°C. The measured maximum output power densities (@0.76V) of this cell reached 588 mW/cm 2 at 700°C by employing hydrogen as fuel and air as oxidant.

Electrodes with a maximal active site density are critical for high‐performance high‐temperature electrochemical cells (HTECs). One widely employed approach involves the use of porous nanostructures with a high surface‐to‐volume ratio. However, their active site densities inevitably decrease owing to particle aggregation induced at high temperatures, necessitating further development of electrode processing techniques. Taking Pt/yttria‐stabilized zirconia (YSZ) interface as a model system, a Pt nanostructured textile akin to the cantaloupe‐rind pattern with high mechanical integrity is fabricated. Application of an AC voltage to this textile electrode at an elevated temperature reduces the Pt particle size from submicron to 10–80 nm forming a nanocomposite with YSZ, accompanied by a 40‐fold increase in current density under high‐temperature water electrolysis conditions. Furthermore, the AC voltage application to a partially aggregated electrode restores its nano‐blended structure associated with the recovery of its activity. This technique is effective in counteracting particle aggregation on demand, providing an alternative approach to achieve high performance and extended lifetimes in HTECs.
