Call for Papers the 243rd ECS Meeting with SOFC-XVIII, Boston, May 28 to June 2, 2023.

BACKGROUND AND AIM: This study aimed to assess maxillary sinus floor membrane thickness and ostium patency (OP) in patients undergoing cone beam computed tomography (CBCT) evaluation for implant placement in the posterior maxilla. Mucosal thickening (MT) could be cause of post-operative complications in implant procedures; awareness of this incidence could help proper detection and further succ...

Introduction: The use of lopinavir/ritonavir (LPV/r) has decreased morbidity and mortality due to human immunodeficiency virus (HIV); however its use could be impaired by hepatotoxicity. Therefore, this study was designed to investigate the effects of melatonin (MT) and alpha lipoic acid (ALA) on LPV/r-induced hepatotoxicity in male albino rats. Methods: Rats were divided into groups and treate...

This paper presents a hierarchical modeling approach for Solid-Oxide Fuel Cells from elementary kinetics to stacks. On a fundamental level, we have developed an analytical model for the evaluation of volume specific three-phase boundary length (vLtpb) in composite electrodes and electrochemical kinetics expressions to account for coverage dependent activation energies of various surface adsorbe...

Oxide diffusion was studied in two innovative SOFC cathode materials, Ba(2)Co(9)O(14) and Ca(3)Co(4)O(9)+δ derivatives. Although oxygen diffusion was confirmed in the promising material Ba(2)Co(9)O(14), it was not possible to derive accurate transport parameters because of an oxidation process at the sample surface which has still to be clarified. In contrast, oxygen diffusion in the well-known...

Composites formed by infiltration of 45 wt % La0.3Sr0.7TiO3 (LST) into 65% porous yttria-stabilized zirconia (YSZ) were examined for application as solid oxide fuel cell (SOFC) anodes. Although LST does not react with YSZ, the structure of the LST deposits was strongly affected by the calcination temperature. At 1373 K, the LST formed loosely packed, 0.1 μm particles that filled the YSZ pores. ...

In this study, a solid oxide fuel cell (SOFC) stack has been successfully fabricated and tested by using direct natural gas. The main objective of this research was to achieve optimal long-term performance of the SOFC stack without carbon deposition by using low-cost natural gas as a fuel. The stack configuration was improved by a new interconnect design and made of cost-effective raw materials...

In this article three dimensional modeling of a planar solid oxide fuel cell (SOFC) was investigated. The main objective was to attain the optimized cell operation. SOFC operation simulation involves a large number of parameters,   complicated equations, (mostly partial differential equations), and a sophisticated simulation technique; hence, a finite element method (FEM) multiphysics approach ...

Converting chemical energy into electricity is done by an electro-chemical device known as a fuel cell. Thermal stress is caused at high operating temperature between 700 oC to 1000 oC of SOFC. Thermal stress causes gas escape, structure variability, crack initiation, crack propagation, and cease operation of the SOFC before its lifetime. The aim of this study is to presen...
