In the present study, solid oxide cells (SOCs) were operated in electricity generation (solid fuel cell, SOFC) mode and hydrogen production electrolysis SOEC) mode. The electrodes fabricated with nickel-gadolinia doped ceria (Ni-GDC) nickel-yttria stabilized zirconia (Ni-YSZ) composites investigated. correlations between changes microstructure degradation of electrochemical performance are discussed. mechanisms correlated Ni phase found to be similar for Ni-GDC Ni-YSZ electrodes. On other...
Abstract Microstructure of electrodes determines the performance electrochemical devices such as fuel cells and batteries. The efficiency economic feasibility these technologies depend on stability microstructures throughout their lifetime. Although modeling techniques were proposed for determining electrode from 2- or 3-dimensional microstructural data, it is still extremely challenging to predict long-term structural degradation by means numerical simulations. One major challenges overcome...
Plug-flow reactors are very common in methane/steam reforming applications. Their operation presents many challenges, such as a strong dependence on temperature and inlet composition distribution. The endothermic steam reaction might result drop at the of reactor. non-uniform distribution due to an chemical can have tremendous consequences reactor, catalyst degradation, undesired side reactions thermal stresses. One possibilities avoid unfavorable conditions control circumstances inside...
A framework for the automatic segmentation of large 3-D datasets microscopic images is designed and tested microstructures solid oxide cells (SOC) electrodes reconstructed using focused ion beam—scanning electron microscopy (FIB-SEM). The developed algorithm utilizes a simple, yet very effective deep neural network based on patch-convolutional layers (patch-CNN) in encoder-decoder configuration. guidelines selection architecture preparing minimizing training dataset are given. proposed...
Abstract The co‐generation of electricity and chemicals via direct internal reforming solid oxide fuel cells (DIR‐SOFCs) offers a promising route to carbon‐neutral energy solutions. However, challenges such as inadequate performance fast degradation, particularly when using hydrocarbon fuels like CH 4 , hinder the deployment DIR‐SOFC technology. This study addresses three critical issues: effect composition on electrochemical properties, mechanisms microstructural impacts carbon deposition,...
Nickel-gadolinium doped ceria (Ni-GDC) composite anodes gain a lot of attention as they have potential to be beneficial solution for the intermediate temperature solid oxide fuel cells. In this paper, influence initial microstructure Ni-GDC anode on polarization characteristics and its deterioration in 100h operation are investigated. The microstructures investigated determined by different sizes aspect ratios GDC powders, but all having same compositions NiO:GDC = 60:40 vol.%. It was found...
The conversion of biogas to electricity presents an attractive niche application for solid oxide fuel cells (SOFCs). A number attempts have been made use as a high temperature cell systems such SOFCs. Biogas can be converted hydrogen-rich in reforming process which steam or carbon dioxide the agent. Conventionally, is conducted at around 850◦C using several different catalysts depending on application. naturally contains agent, dioxide, however, typical content insufficient conduct safely....
