Influence of the ratio between Ni and BaCe0.9Y0.1O3−δ on microstructural and electrical properties of proton conducting Ni–BaCe0.9Y0.1O3−δ anodes

Processing and characterizations of a novel proton-conducting BaCe0.35Zr0.50Y0.15O3-δ electrolyte and its nickel-based anode composite for anode-supported IT-SOFC

“…Figure 10 shows the Arrhenius plot of DC conductivity in the temperature range of 350-800°C, where the conductivity decreases with increase in temperature showing a metallic behavior, may be due to well dispersion of nickel particle in the sample. The conductivity of Ni-BCZY composite (prepared by LCP) varies between 1,050 and 1,590 S cm -1 in the measured temperature range, which is found to be much higher than that of Ni-YSZ based anodes used in conventional SOFCs [19][20][21][22] and Ni-BCY based anodes used in protonic SOFCs [23,24]. This indicates that, as far as electrical conductivity is concerned, the Ni-BCZY composite prepared by LCP method could be a suitable anode material for the SOFC to run at lower temperatures.…”

Heat Treatment Effect on the Phase and Morphology of NiO-BCZY Prepared by an Evaporation and Decomposition of Solution and Suspension Method

“…The results is in line with the work done by Yan et al (2010) which also employed the nitrate-based nickel as the precursor material in preparing composite anodes of Ni-BCZY via a mechanical mixing powder method. Furthermore, detailed literature survey showed that homogenize composite anode prepared via EDSS method can only be formed if the ceramic part of the anode has three metal elements such as (2013) and Zunic et al (2011). All their prepared samples were calcined at T = 800°C to 1100°C.…”

“…This technique enables mixing of precursors in the starting solution, resulting in a gel mixture with high degree of homogeneity (Aruna et al 1998;Marinšek et al 2000;Yan et al 2010). Additionally, properties of the produced powders via the techniques are also affected by the metal salts precursor used, heat treatment profiles and composition of the cermet or electrolyte materials (Narendar et al 2013;Ng et al 2016;Osman et al 2009;Yamaguchi et al 2016;Zunic et al 2014Zunic et al , 2011.…”

“…Usually, EDSS method is used to prepare cermet which consists of three metal elements in its ceramic compound or electrolyte parts such as NiBaCeYO 3 (Zunic et al 2011), Ni-BaZrYO 3 (Narendar et al 2013) and Ni-YSZ (Xi et al 2014). However, there are scarce of works reported on the production of cermet which consists of four metal elements in its ceramic part such as NiO-BaCe 0.54 Zr 0.36 Y 0.1 O 2.95 (NiO-BCZY) particularly by the EDSS method.…”

In-situ redox cycling behaviour of Ni–BaZr0.85Y0.15O3−δ cermet anodes for Protonic Ceramic Fuel Cells

“…For PCFCs, the potential anode materials Ni-Ba(Ce,Y)O 3- (Ni-BCY) [5,6], NiBa(Zr,Y)O 3- (Ni-BZY) [7], Ba(Ce,Zr,Y,Yb)O 3- [8], Ni-SrCe 0.9 Yb 0.1 O 3-δ [9] Ca(Zr,Y)O 3- , Ni-Sr(Zr,Y)O 3- [10] and Ni-Ba(Ce,Zr,Y)O 3- [11][12][13][14] have been reported in the literature. Due to the instability of BCY in H 2 O and CO 2 containing atmospheres, cermet anodes of Ni-BCY may be unsuitable for practical operation in alternative carbonaceous fuels [4].…”
