A key obstacle to practical operation of protonic ceramic fuel cells (PCFCs) is the development of high efficient cathode materials. In this study, we report the identification of Gd0.1Ce0.9O2-d (GDC) infiltrated PrBaCo2O5þd (PBC) e BaZr0.1Ce0.7Y0.2O3-d (BZCY) materials as a novel triple phase (e /Hþ/O2 ) conducting composite cathode of PCFCs. This triple phase conducting composite cathode is c...
In this paper, the effects of infiltration of La2NiO4 (LNO) as a mixed ionic and electronic conductor (MIEC) on the electrochemical performance of porous strontium doped lanthanum manganite (LSM) oxygen electrode of solid oxide cells, in the temperature ranges of 650-850 °C, is reported. XRD and FE-SEM results of the LNO sample calcined at 900 °C confirmed the formation of single phase LNO nano...
A BaO infiltrated La0.6Sr0.4Co0.2Fe0.8O3-δ (LSCF) cathode shows remarkable tolerance and resistance towards chromium via the formation of BaCrO4 instead of SrCrO4 on the electrode surface, preventing the excess Sr deficiency at the A-site of LSCF perovskite and thus mitigating the Cr poisoning effect.
a novel silver (ag) nanocomposite electrode was proposed that fabricated from metal nanostructures and ionic liquids. the combined application of unique properties of nanomaterials and ionic liquids in the design of this ag nanocomposite results in electrodes with interesting advantages compared to the conventional metal disk electrode. in the first part of this thesis, the elecrocatalytic eff...
Metallic glass (MG) assists electrical contact of screen-printed silver electrodes and leads to comparable electrode performance to that of electroplated electrodes. For high electrode performance, MG needs to be infiltrated into nanometer-scale cavities between Ag particles and reacts with them. Here, we show that the MG in the supercooled state can fill the gap between Ag particles within a r...
Semiconducting single-walled carbon nanotube/fullerene bulk heterojunctions exhibit unique optoelectronic properties highly suitable for flexible, efficient, and robust photovoltaics and photodetectors. We investigate charge-transfer dynamics in inverted devices featuring a polyethylenimine-coated ZnO nanowire array infiltrated with these blends and find that trap-assisted recombination dominat...
Previous fiber-shaped solar cells are based on polymeric materials or dye-sensitized wide band-gap oxides. Here, we show that efficient fiber solar cells can be made from semiconducting nanostructures (e.g. CdSe) with smaller band-gap as the light absorption material. We directly grow a vertical array of CdSe nanowires uniformly around a core metal wire and make the device by covering the top o...
