Applications of nano-composite materials for improving the performance of anode-supported electrolytes of SOFCs

Effect of the anode microstructure on the enhanced performance of solid oxide fuel cells

“…5(b) suggested similar natures, the lack of the percolation of the phases resulted in disconnected reaction sites in the anode of the cell A. Therefore, improved percolation of all of the three phases resulted in a relatively higher amount of active reaction sites and higher electrical conductivity which gave rise to the performance of the cell B [58].…”

Dip-coating of 8YSZ nanopowder for SOFC applications

“…Dipcoating is a cost-effective wet-chemical method which has been used widely in the literature to obtain thin layers [13][14][15][16][17][18][19][20][21][22]. In dip-coating a porous substrate is immersed in a liquid in which the particles to be deposited are suspended.…”

“…Using nanopowders as precursors for the manufacture of SOFC electrodes have been demonstrated to enhance the triple phase boundary and thereby improving the performance of anodesupported cells [16,21]. Sintering of nanograined particles may take place at lower temperatures [10,[22][23][24], which is interesting for both the electrolyte and the electrode-supported configurations.…”

Examination of the co-sintering process of thin 8YSZ films obtained by dip-coating on in-house produced NiO–YSZ

“…[2][3][4][9][10][11][12] Dipcoating is a wet-chemical process that has been used widely in order to obtain thin films. [13][14][15][16][17][18][19][20][21][22][23][24] It is a low-cost method that can be scaled for industrial purposes. The substrates used for dip-coating can have planar, cylindrical or complex geometries.…”

“…It has been shown that by using NiO-YSZ nano-composite powder the performance and durability of single SOFC cells are improved due to homogeneous structure and larger thriple-phase boundaries, TPBs. [15][16][17]19,24 In this work, NiO-YSZ nanoparticles were obtained via a modified sol-gel method using sucrose and pectin as organic precursors. It has been demonstrated in earlier work that nanoparticles suitable for the SOFC application can be manufactured with this method.…”
