“…Among various lanthanide oxide materials, Gd 2 O 3 was found to be the best additive for the Ni anode performance enhancement of direct carbon fuel cell (DCFC) [3]. Also, Gd 2 O 3 is used as an electrolyte material for SOFCs when it is composited with Bi 2 O 3 and CeO 2 [1]. On the other hand, rare earth (RE) oxides, especially Gd 2 O 3 , have been adopted as excellent host lattice for many transition metal activator ions [4].…”

“…As environmentally friendly and highly efficient energy conversion devices that directly convert the chemical energy of fuels into electricity, solid oxide fuel cells (SOFCs) have attracted lots of attention [1]. Furthermore, Solid oxide fuel cells (SOFCs) hand in hand with the utilizing of solid oxide to improve the performance of fuel cells are a feasible next-generation, environmentally friendly, renewable energy source due to their minimal pollution, high operating efficiency and fuel flexibility for domestic and large-capacity applications [2,3].…”

“…Penurunan densitas bisa disebabkan oleh membesarnya parameter kisi akibat distorsi kisi yang dapat memperlambat pergerakan kation sehingga menyebabkan penurunan densitas. Densifikasi sendiri dapat terjadi melalui difusi batas butir [18,19].…”

“…The presence of SiO 2 impurity is ubiquitous in precursor materials and can be also introduced from furnace refractories during high temperature sintering. In order to improve the GB conductivity, many attempts have been made to scavenge the highly resistive siliceous phase through adding various additives such as Bi 2 O 3 [11,12] and Al 2 O 3 [13,14]. Bi 2 O 3 and Al 2 O 3 have been identified to be the effective additives in improving the GB conductivity of zirconia-based electrolytes.…”
