Theoretical Verification Necessity of Leakage Currents Using Sm Doped Ceria Electrolytes in SOFCs
Numerous approaches have been made to solve the basic transport equation that describes a solid oxide fuel cell (SOFC) with mixed conduction. Classically, the open circuit voltage (OCV) is calculated with Wagner‘s equation, which is right within the limits of linear transport theory. In order to generalize Wagner’s equation, many models have been proposed to describe the current-voltage relatio...
متن کاملThe Industrial Necessity of Leakage Current Verification Using Sm Doped Ceria Electrolytes in SOFCs and Future Applications
The use of Sm-doped Ceria electrolytes (SDC) in SOFCs (solid oxide fuel cells) lowers the open circuit voltage (OCV) below the Nernst voltage (Vth) obtained using Yttria-stabilized Zirconia (YSZ) electrolytes. The OCV is classically calculated with Wagner’s equation. However, using the SDC electrolytes requires both qualitative and quantitative experimental verification of leakage currents. Fur...
متن کاملFrequencies of HLA-E*01:01/*01:03 Alleles in an Iranian Healthy Population and Its Comparison with Hyperglycemia Patients
Background and Aims: The human leukocyte antigen-E (HLA-E) is a member of non-classical HLA class-I genes which is highly conserved through evolution. In general, so far 25 alleles of HLA-E have been described. However, the existence of only two allelic group; HLA-E*01:01 and HLA-E*01:03 have been demonstrated in all the populations. HLA-E*01:01 and HLA-E*01:03 differ only at codon 107 of exon ...
متن کاملLoss of Gibbs Energy Using Sm-Doped Ceria Electrolytes in SOFCs Considering Local Equilibrium while Ion Hopping
Using Sm-doped Ceria electrolytes (SDC) in SOFCs (solid oxide fuel cell), the open circuit voltage (OCV) becomes lower than the Nernst voltage (Vth), which is obtained using Yttria-stabilized Zirconia (YSZ) electrolytes. Classically, OCV is calculated with Wagner’s equation. However, experimental verification of leakage currents using SDC electrolytes is necessary, both qualitatively and quanti...
متن کاملAssociation between HLA-DQB1*03:01 and Bullous Pemphigoid in Iranian Patients
Background: A common Human Leukocyte Antigen (HLA) class II allele, DQβ1*03:01, seems to be associated with Bullous pemphigoid (BP) in Caucasians whereas previous studies in other ethnic groups showed other HLA class II alleles as genetic predisposing factors for BP. Objective: To investigate the association of HLA class II alleles and haplotypes with BP in Iranian population. Methods: Fifty pa...
