Title: Degradation Comparison of Cyclic and Linear Siloxane Contamination on Solid Oxide Fuel Cells Ni-YSZ Anode

Abstract

The solid oxide fuel cell (SOFC) nickel-yttria stabilized zirconia (Ni-YSZ) anode degradation due to different types of siloxane contamination is investigated. A cyclic structure siloxane, octamethylcyclotetrasiloxane (D4), and a linear structure siloxane, decamethyltetrasiloxane (L4), are mixed with H ₂ +N ₂ as the fuel for SOFCs at 750°C. The electrochemical characterization results after stability experiments suggest that the SOFC contaminated with cyclic siloxane, D4, had higher degradation. Pure YSZ pellets with different surface hydroxylation extents were also tested to investigate the D4/L4 adsorption and deposition process. Postmortem SEM/WDS, XRD and Raman analysis all indicate that cyclic siloxane has more deposition than linear siloxane on the anode. Further analysis demonstrates that high adsorption and low desorption rates of cyclic siloxane on YSZ are linked to the degradation. Besides the silicon deposition, SiC and amorphous carbon deposition were also observed from the XRD and Raman analysis.

Siloxane Deposition on the Ni-YSZ Solid Oxide Fuel Cell Anode Exposed to Bio-Syngas

Journal Article Tian, Jiashen ; Milcarek, Ryan J. - Journal of the Electrochemical Society

Siloxane, a common contaminant present in biogas, is known for adverse effects on cogeneration prime movers. In this study, the siloxane deposition products and mechanism in the solid oxide fuel cell nickel-yttria stabilized zirconia (Ni-YSZ) anode are investigated analytically and experimentally. An SOFC with Ni-YSZ anode and pure Ni/YSZ pellets were exposed to a simulated biogas-reformate fuel with octamethylcyclotetrasiloxane (D4) contamination at 750 °C. The electrochemical characterization results show that the SOFCs performance degradation caused by D4 contamination is irreversible. Morphology and XRD results illustrate that silicon and carbon deposition can both be detected in the anode and pellets. Graphite,more »« less

Investigating the degradation mechanism of the solid oxide fuel cell nickel-yttria stabilized zirconia anode under siloxane contamination

Journal Article Tian, Jiashen ; Milcarek, Ryan J. - Journal of Power Sources

In order to investigate the solid oxide fuel cell nickel-yttria stabilized zirconia (Ni-YSZ) anode degradation mechanism due to poisoning by Octamethylcyclotetrasiloxane (D4), four different experiments utilizing H₂+H₂O, H₂+H₂O+D4, H₂+D4 and H₂+CO+D4 as fuels at 750 °C are conducted in this study. The electrochemical characterization and morphology results are analyzed and compared for anode degradation phenomenon. The results contradict the previously proposed degradation mechanism as the experimental results show that water can inhibit the silicon deposition and anode degradation. Based on the experimental results in this study and previous studies about siloxane deposition on metal oxides, a new anode degradation mechanismmore »« less

Investigating the Influence of Ni, ZrO₂, and Y₂O₃ from SOFC Anodes on Siloxane Deposition

Journal Article Tian, Jiashen ; Milcarek, Ryan J. - ECS Journal of Solid State Science and Technology

Siloxanes, as a type of impurity in biogas, can poison the Ni-YSZ anode of SOFCs. However, the influence of individual components of the anode, such as Ni, ZrO₂, and Y₂O₃, on the siloxane deposition process has not been investigated extensively. In this study, Ni, ZrO₂, and Y₂O₃ pellets were exposed to H₂ + N₂ + H₂O + D4 (octamethylcyclotetrasiloxane, 2.5 ppmv) and H₂ + N₂ + D4 (2.5 ppmv siloxane) gas mixtures at 750 °C to investigate their affinity and tolerance for siloxane degradation. Surface morphology analysis and electrochemical analysis including electrochemical impedance spectroscopy (EIS), related distribution of relaxation times (DRT) analysis and equivalent circuit modeling with complex nonlinear least square (CNLS) fitting were conducted.

The Detection of Monoclinic Zirconia and Non-Uniform 3D Crystallographic Strain in a Re-Oxidized Ni-YSZ Solid Oxide Fuel Cell Anode

Journal Article Heenan, Thomas M. ; Vamvakeros, Antonis ; Tan, Chun ; ... - Crystals

The solid oxide fuel cell (SOFC) anode is often composed of nickel (Ni) and yttria-stabilized zirconia (YSZ). The yttria is added in small quantities (e.g., 8 mol %) to maintain the crystallographic structure throughout the operating temperatures (e.g., room-temperature to >800 °C). The YSZ skeleton provides a constraining structural support that inhibits degradation mechanisms such as Ni agglomeration and thermal expansion miss-match between the anode and electrolyte layers. Within this structure, the Ni is deposited in the oxide form and then reduced during start-up; however, exposure to oxygen (e.g., during gasket failure) readily re-oxidizes the Ni back to NiO, impedingmore »« less
