Enhanced power density of metal-supported solid oxide fuel cell with a two-step firing process

Flexible solid oxide fuel cells supported on thin and porous metal

“…3b). It has been previously confirmed that the anodic structure is very critical to the performance of metal-supported cells [21]. Therefore, the performance of the NiFe-supported cell can be further enhanced by controlling the anodic microstructure.…”

“…Then the tapes were punched out to have a diameter of 25 mm. The three-layered cell was co-fired using two-step firing process [21]. The green cells were fired at or below 400 C in air for 5 h to burn binder (heating rate: 2 C/min) and further fired at 1300 C in air for 3 h (3 C/min) in the first step.…”

Solid oxide fuel cell with Ni–Al support

“…One of the highest values among the MS-SOFCs based on YSZ electrolyte was obtained by Hyoup Je Cho et al [33] for a cell with metallic support from pure Ni which showed a maximum power density of 930 mW cm À2 at 800 C.…”

Metal-supported Solid Oxide Fuel Cell with La0.4Sr0.6Co0.2Fe0.7Nb0.1O3-δ Cathode

“…In order to obtain dense electrolyte without the metal support being oxidized, costly layer deposition techniques were applied known as PLD (Pulse Laser Deposition) and APS (Atmospheric Plasma Spray) (3)(4). Traditional high temperature sintering (1350-1450 o C) have also been used to prepare dense electrolyte layer on metal oxide support, followed by reduction in reducing atmosphere to get the oxide support reduced (5). On the other hand, the cathode layer deposition was usually conducted in air and high sintering temperature typically above 1000 o C, which in turn would lead to the oxidation of the as-reduced metal support.…”
