Catalyst-infiltrated supporting cathode for thin-film SOFCs

Abstract: The fabrication and electrochemical performance of co-fired, LSM-SYSZ [i.e. using humidified hydrogen as a fuel. Co-firing of bi-layers and tri-layers was successful at 1250˚C by optimizing the amount of carbon pore formers. A power density of a factor of 2.5 higher than that recently reported for the same type of cell at 800˚C [3] was obtained for a cell with cobalt infiltration into the supporting cathode: the peak power densities were 455, 389, 285, 202, 141 mW/cm 2 at 800, 750, 700, 650, 600˚C, respectivel… Show more

“…31 Although studies of CoO x -treated LSM-and LSCF-based cathodes have been well documented, there is no consensus regarding the performance of LSC cathodes surface treated with CoO x . [21][22][23]32,33 As such, in this work, we studied the effect of ALD cobalt oxide (CoO x ) treatment on an LSC cathode based on an anode-supported SOFC cell. The low deposition temperature used in this study (200 • C) results in minimal 3-dimensional change in the cathode structure during modification.…”

“…Cathode supported cells are considered advantageous because of the reduced risk of carbon poisoning in thin anode layers when hydrocarbon fuel is used [44], furthermore, the risk of Ni oxidation by water is reduced in thin anode layers [45], in addition to the ohmic polarisation as a result of the thin electrolyte thickness.…”

“…Previous literature demonstrates the effectiveness of the nanocatalyst impregnation in SOFC cathodes for improving oxygen reduction reaction [1,[5][6][7][8][9][10][11]; unfortunately, the impregnation process may be time and labor intensive to incorporate the required nano-catalyst content within the open porosity. A well connected deposition of nano-catalyst into an electrode is typically only achieved by repetitive impregnation steps, which leads to more costly processing [11].…”
