Electrochemical processes in (La1-xSrx)2(Ni0.9Mn0.1)O4+? based air electrodes for solid oxide cells

Yatir Sadia et al.

Summary: Solid oxide fuel cells are a promising alternative to fossil-fuel based energy. Improving the performance of mixed ionic-electronic conducting cathodes at lower temperatures is a major challenge. This study focuses on a cathode based on La2NiO4 with Sr and Mn replacements, and uses electrochemical impedance spectroscopy and distribution of relaxation time analysis to identify and study different processes. Three processes – oxygen diffusion, oxygen surface exchange and charge transfer, and oxygen transfer through the electrode/electrolyte interface – were identified and analyzed.

Application of finite Gaussian process distribution of relaxation times on SOFC electrodes

Nicholas J. Williams et al.

Summary: Electrochemical impedance spectroscopy (EIS) is a powerful tool for understanding electro-chemical systems, and the distribution of relaxation times (DRT) calculation allows us to identify and analyze relaxation processes occurring in the system. By using Gaussian process (GP) regression, we propose a method to find a unique solution to the ill-posed DRT problem. Our analysis on EIS data from a solid-oxide fuel cell reveals the current-voltage relationship and sheds light on the charge transfer mechanism at the solid-gas interface.

Proton-conducting solid oxide electrolysis cells: Relationship of composition-structure-property, their challenges, and prospects

Muhammad Bilal Hanif et al.

Summary: Proton-conducting solid oxide electrolysis cells (H-SOECs) have gained significant attention due to their advantages over ion-conducting SOECs (O-SOECs). However, progress in H-SOECs lags behind O-SOECs, primarily due to the low stability of electrolytes in environments with H2O and CO2. This review critically evaluates recent developments in H-SOECs and discusses future research directions.

Call attention to using DRT and EIS to quantify the contributions of solid oxide cell components to the total impedance

Yudong Wang et al.

Summary: This study investigated the contributions of anode and cathode processes to the impedance of solid oxide fuel cells (SOFC) using electrochemical impedance spectroscopy (EIS) and distribution of relaxation time (DRT). It was found that both electrodes contributed to multiple peaks simultaneously, and two different operating conditions could yield equivalent DRT spectra. Extra consideration is needed when evaluating and quantifying the anodic and cathodic resistances in SOFCs.
