“…They also show that for SOFC fuel utilization rates of 55% or less, the integrated reforming process can be sustained through the heat generated by the SOFC and flue gas combustion. Miyake et al, showed that the syngas produced from biogas reforming over Ni/LaAl 2 O 3 catalyst is an effective feedstock for the SOFC process [15]. Biogas reforming processes coupled with fuel cell systems studied by Farhad et al, [16] and Trendewicz et al, [17] achieved 42.4% and 51.6% electricity generation efficiency, respectively.…”

“…The performance of these nanocomposite-based cells is much higher than that of Ni and Ni−Cu based anode catalysts with biogas fuel, as reported by Miyake et al and Papadam et at. 51,52 Also, it has been observed in both cases that the OCV and performance of all three samples were stable. Figure 8b, further demonstrates that the polarization behavior of fuel cells is identical with both hydrogen and biogas fuels.…”

The development of active catalysts is always challenging in the field of energy devices. In this work, Li-doped, Ni−Cu-based, and Ni-free nanocomposite anode catalysts are synthesized and studied for solid-oxide fuel cells (SOFCs) operated at a low temperature using hydrogen and biogas as fuels. The catalysts with compositions Ni 0.6 Li 0.2 Cu 0.2 -oxide/ La 0 . 2 Ce 0 . 8 O 2δ (NLC622-LDC), Ni 0 . 2 Li 0 . 2 Cu 0 . 6 -oxide/ La 0.2 Ce 0.8 O 2-δ (NLC226-LDC), and Ni 0.0 Li 0.2 Cu 0.8 -oxide/ La 0.2 Ce 0.8 O 2-δ (NLC028-LDC) are synthesized using the glycerol-assisted gel combustion route (GGCR). The structural analysis revealed the cubic structure of metallic oxide materials such as NiO and CuO phases while the cubic fluorite structure of CeO 2 as an ionic oxide phase. The optical band gaps (E g 's) of anode catalysts NLC622-LDC, NLC226-LDC, and NLC028-LDC are found to be 2.08, 2.29, and 2.37 eV, respectively. Furthermore, the anode catalyst with a higher nickel concentration shows better electrical conductivity and a lower activation energy of 3.47 S cm −1 and 0.67 eV at 600 °C, respectively, as compared to those of a nickel-free anode catalyst with lower nickel content. The electrochemical behavior of nanocomposites is studied at 600 °C using Nyquist plots. Electrochemical impedance analysis is carried out to see the effect of hydrocarbon fuel like biogas at the anode side. Finally, the electrochemical performance of NiLiCu-LDC catalyst-based fuel cells is tested under hydrogen and biogas fuels. Overall, the fuel cell based on the NLC622-LDC anode catalyst has higher OCV and power density with both fuels, hydrogen and biogas. Therefore, NLC622-LDC is a highly catalytically active anode catalyst which demonstrated significantly better performance for SOFCs operated at a low temperature (500−600 °C) without any carbon resistance.

“…For example, methane-rich bio-gas can be converted to H 2 and CO through reform processes like the steam reforming process, dry reforming process or partial oxidation reforming process using a separate reform device in front of SOFC [152]. The direct internal reforming process of SOFC can also be realized by mixing oxygen, water and other reforming agents into the fuel gas [154]. Bio-gas is rich in CO 2 , which reduces the calorific value, but also creates conditions for direct internal dry reforming of methane.…”

“…Methane can be effectively reformed into hydrogen and CO in situ with catalysis of the catalyst layer loaded on the anode. Proton conducting materials [148], perovskites [146], transition metals [154] and transition metal oxides [156] are selected to catalyze the direct inner dry reform process. In addition, adding a certain amount of N 2 into the fuel gas can obviously improve the stability of the SOFC [149] .…”
