Electrochemical performance of a copper-impregnated Ni–Ce0.8Sm0.2O1.9 anode running on methane

Electroless plated Cu–Ni anode catalyst for natural gas solid oxide fuel cells

“…Cu has low catalytic activity for C H dissociation and C C formation and high electronic conductivity to maintain the fuel cell performance [12]. A number of methods have been reported for the addition of Cu to the Ni/YSZ anode including impregnation of Cu nitrate precursors [13], Cu electroplating [14], microwave irradiation from a Cu nitrate solution [15], and vacuum-assisted Cu electroless plating [16]. Electroless plating is a low cost technique to prepare a uniformly deposited layer of metals.…”

NiMo‐Ceria‐Zirconia Catalyst for Inert‐Substrate‐Supported Tubular Solid Oxide Fuel Cells Running on Model Gasoline

“…[1][2][3] The direct hydrocarbon fueled SOFCs show advantages of simplicity and high overall efficiency (40-50 %). [11][12][13][14] To address these problems, it is necessary to apply active catalysts in SOFC single cells to effectively reform the hydrocarbon fuels into simple syngas (a mixture of hydrogen and carbon monoxide), and suppress the carbon deposition. Thus, in view of fuel cell commercialization, it is important to develop SOFCs running on complex hydrocarbon fuels (e. g., gasoline).…”

“…Figure 2 (b) shows corresponding Nyquist plots of the single cell in hydrogen and isooctane/air, respectively. [14,[36][37][38] The electrochemical parameters derived from the impedance spectra fittings are listed in Table 1. L is the inductance element, and R ohm is the ohmic resistance of the entire cell.…”

“…[8][9][10] However, when using complex hydrocarbon as fuels, severe carbon deposition on the Ni deactivates the electrochemical properties of the anode for fuel oxidation, and the chemical reaction between Ni and carbon deposits leads to the structure instability of the anode and cracking of the single cell. [11][12][13][14] To address these problems, it is necessary to apply active catalysts in SOFC single cells to effectively reform the hydrocarbon fuels into simple syngas (a mixture of hydrogen and carbon monoxide), and suppress the carbon deposition. On the other hand, a novel single cell configuration with high mechanical property is desired to improve the structure stability.…”

“…The polarization resistance (R p ) is the sum of R H and R L . [14,[36][37][38] The electrochemical parameters derived from the impedance spectra fittings are listed in Table 1.…”
