Title: Enhanced surface exchange activity and electrode performance of (La_2–2xSr_2x)(Ni_1–xMn_x)O_4+δ cathode for intermediate temperature solid oxide fuel cells

Abstract

Surface exchange kinetics of Ruddlesden-Popper (R-P) phase lanthanum nickelates upon Mn doping as an intermediate temperature solid oxide fuel cells (IT-SOFCs) cathode is investigated for the first time in this communication. To promote the exchange rate in oxygen reduction reaction (ORR) on nickelates, Mn is partially substituted for Ni. The oxygen exchange resistance is accurately measured by electrochemical impedance spectroscopy (EIS) with dense thin layer cathode. It is found that Mn substantially promotes the surface kinetics; a surface exchange coefficient (k) of 1.57 × 10^–6 cm/s is obtained at 700 °C for La_1.8Sr_0.2Ni_0.9Mn_0.1O_4+δ (Sr20Mn10), ~80% higher than that of the undoped La₂NiO_4+δ (LNO). To our best knowledge, such coefficient is the highest values among the currently available R-P phase IT-SOFC cathodes. The corresponding polarization resistances (R_p) are evaluated on porous electrodes. R_p for LNO is 0.74 Ωcm² at 750 °C, but decreases significantly to 0.42 Ωcm² for Sr20Mn10 which is remarkably improved compared to the reported values in the literature for La₂MO_4+δ materials (M = transition metal). In conclusion, those promising results demonstrate that Mn-doped LNO is a new excellent cathode material for IT-SOFC.

Oxygen reduction reaction kinetics in Sr-doped La₂NiO_4+δ Ruddlesden-Popper phase as cathode for solid oxide fuel cells

Journal Article Guan, Bo ; Li, Wenyuan ; Zhang, Hui ; ... - Journal of the Electrochemical Society

In this study, electro-catalytic reduction of oxygen in Sr-doped lanthanum nickelates, La_2-xSr_xNiO_4+δ (0 ≤ x ≤ 0.4) Ruddlesden-Popper (R-P) phase, has been investigated. The oxygen reduction reaction (ORR) kinetics is evaluated via electrochemical impedance spectroscopy (EIS) with the symmetric cell configuration. The maximum performance is achieved with the un-doped La₂NiO_4+δ, ~0.13 Ωcm² at 800°C. Sr doping decreases the electrode performance progressively. Further detailed analysis indicates that bulk ionic diffusion and surface oxygen exchange co-limit the ORR of those cathodes. Sr substitution leads to both lowered bulk diffusion and surface exchange rates. With high Sr content (x = 0.3, 0.4), oxygenmore »« less

New mechanistic insight into the oxygen reduction reaction on Ruddlesden–Popper cathodes for intermediate-temperature solid oxide fuel cells

Journal Article Li, Wenyuan ; Guan, Bo ; Zhang, Xinxin ; ... - Physical Chemistry Chemical Physics. PCCP

Ruddlesden–Popper (R–P) phase materials have been investigated widely as cathode candidates for IT-SOFCs. However, widespread application of R–P phase cathodes demands further improvement in electrode activity whose progress is hindered by the limited information in the oxygen reduction reaction (ORR). The ORR mechanism for the R–P phase is therefore investigated in this paper using (LaSr)₂NiO_4±δ as an example. Accurate characterization of the surface oxygen exchange process is realized by developing thin and dense polycrystalline LSNO layers via a versatile spray-modified pressing method we invented before to avoid perceptible bulk diffusion contribution, surface enrichment and geometry complication. Hence, the governing factorsmore »« less

Surface oxygen exchange properties of Sr doped La₂NiO_4+δ as SOFC cathode: Thin-film electrical conductivity relaxation investigation

Journal Article Guan, Bo ; Li, Wenyuan ; Zhang, Xinxin ; ... - ECS Transactions (Online)

La_2-xSr_xNiO_4+δ dense films are prepared by a novel spray-modified pressing method. The surface reaction kinetics is investigated via electrical conductivity relaxation (ECR). The layer thickness, 5~10 μm, is much less than the characteristic length of lanthanum nickelates, resulting in surface-controlled situation and allowing more accurate fitting than the traditional pellets ECR on the surface exchange coefficient (k). k for LNO is 1.6×10^-5 cm/s in 0.2 atm at 700°C. Sr doping impairs the exchange kinetics, and k of Sr40 is about one order of magnitude smaller than undoped one. Interstitial oxygen and Ni oxidation state are suggested the predominant roles inmore »« less

Mechanism for enhanced oxygen reduction kinetics at the (La,Sr)CoO_3–δ/(La,Sr)₂CoO_4+δ hetero-interface

Journal Article Han, Jeong Woo ; Yildiz, Bilge - Energy & Environmental Science

The recently reported fast oxygen reduction kinetics at the interface of (La,Sr)CoO_3–δ (LSC₁₁₃) and (La,Sr)₂CoO_4+δ(LSC₂₁₄) phases opened up new questions for the potential role of dissimilar interfaces in advanced cathodes for solid oxide fuel cells (SOFCs). Using first-principles based calculations in the framework of density functional theory, we quantitatively probed the possible mechanisms that govern the oxygen reduction activity enhancement at this hetero-interface as a model system. Our findings show that both the strongly anisotropic oxygen incorporation kinetics on the LSC₂₁₄ and the lattice strain in the vicinity of the interface are important contributors to such enhancement. The LSC₂₁₄(100)more »« less

High performance La₂NiO_4+δ-infiltrated (La_0.6Sr_0.4)_0.995Co_0.2Fe_0.8O_3–δ cathode for solid oxide fuel cells

Journal Article Zhang, Xinxin ; Zhang, Hui ; Liu, Xingbo - Journal of Power Sources

In this paper, we reported our effort on improving electrochemical performance of (La_0.6Sr_0.4)_0.995Co_0.2Fe_0.8O_3–δ (LSCF) cathode in solid oxide fuel cell (SOFC) by infiltration of La₂NiO_4+δ(LNO). It is found that a porous LSCF backbone coated with LNO nanoparticles is an attractive way to acquire a noticeable decrease in the polarization resistance and activation energy of LSCF cathode, thereby showing high surface activity and enhanced oxygen transport capability. The key contributions of the LNO nanoparticles also lead to a 67% increase in peak power density and operation stability at a constant current density of 250 mA cm^–2 with a low degradationmore »« less
