Semiconductor ionic electrolytes, especially heterostructure composites, have a significant role in enhancing oxide ion conductivity and peak power density (PPD) because of their interfacial contact. In this work, the fluorite structure CeO2 spinel-based CoAl2O4 samples, as composite electrolyte, are successfully fabricated. The p-type n-type (CeO2-CoAl2O4) used an electrolyte exhibits cell per...

One of the most appropriate electricity production systems is solid oxide fuel cells (SOFCs), which are important because they highly efficient, flexible to fuel, and have fewer environmental degradation effects. A new optimum technique has been provided for providing well-organized unknown parameters identification cell system. The main idea achieve lowest amount sum square error between model...

The MIT Faculty has made this article openly available. Please share how this access benefits you. Your story matters. 5 The correlation between the surface chemistry and electronic structure is studied for SrTi 1-x Fe x O 3 (STF), as a model perovskite system, to explain the impact of Sr segregation on the oxygen reduction activity of cathodes in solid oxide fuel cells. Dense thin films of SrT...

COVID-19 was identified all over the world as a pandemic in December 2019. This novel coronavirus affects lower respiratory area, which causes pneumonia human body and transfers from to human. Every day, number of new patients deaths are increasing immensely, while specific drugs for this virus still being developed. Hospitals struggling accommodate patients, resulting large temporary hospitals...

The success of distributed power generation by plants based on solid oxide fuel cells (SOFCs) is hindered by reliability problems that can be mitigated through an effective fault detection and isolation (FDI) system. However, the numerous operating conditions under which such plants can operate and the random size of the possible faults make identifying damaged plant components starting from th...

One of the major advantages SOFCs is their high fuel flexibility. Next to natural gas and hydrogen, which are today's most common fuels for SOFC-systems cell-/stack-testing respectively, various other applicable as well. In literature, a number promising results show that available propane, butane, ammonia, gasoline, diesel etc. can be applied. Here, performance an anode supported cell operated...

it is expected that residential units may replace   traditional heat and power production systems with cogeneration ones. among the different cogeneration systems, fuel cell based systems are a suitable choice due to their high efficiency, high power density, low emission and low noise. in this paper, a cogeneration system based on solid oxide fuel cells is examined. the system, including the f...
