Mesoporous NiO-samaria doped ceria for low-temperature solid oxide fuel cells
Journal of Nanoscience and Nanotechnology
|May 5, 2015
Summary
Researchers developed mesoporous Nickel-Samarium Doped Ceria (NiO-SDC) as a novel anode material for low-temperature solid oxide fuel cells (SOFCs). This material enhances the triple-phase boundary (TPB) for improved fuel cell performance.
Area of Science:
- Materials Science
- Electrochemistry
- Energy Conversion
Background:
- Development of efficient anode materials is crucial for low-temperature solid oxide fuel cells (SOFCs).
- Achieving a wide triple-phase boundary (TPB) is essential for optimal SOFC anode performance.
Purpose of the Study:
- To synthesize mesoporous NiO-SDC anode material for low-temperature SOFCs.
- To evaluate the performance of Ni-SDC anode-supported SOFC single cells.
Main Methods:
- Mesoporous NiO-SDC synthesized using cetyltrimethyl-ammonium bromide (CTAB) surfactant.
- Ni-SDC anode-supported SOFC single cells fabricated with YSZ electrolyte and LSM cathode.
- Microstructural characterization using XRD, EDX, SEM, and BET; performance evaluated at 600 °C.
Main Results:
- Mesoporous NiO-SDC with 10 nm pores was successfully synthesized.
- Surface area ranged from 90-117 m²/g for NiO-SDC with 35-45 wt% Ni after calcination.
- Optimum Ni content of 45 wt% yielded a maximum power density (MPD) of 0.36 W/cm².
Conclusions:
- Mesoporous NiO-SDC exhibits high surface area suitable for wide TPB in SOFC anodes.
- The Ni content significantly influences surface area and electrical performance.
- Mesoporous NiO-SDC is a promising anode material for low-temperature SOFC applications.
