Performance of Intermediate Temperature SOFCs with Composite Electrolytes

Composite Electrolytes and electrodes for Intermediate Temperature Hybrid Fuel Cells

Moving away from conventional solid oxide electrolytes, hybrid fuel cells based on composite electrolytes (a solid oxide electrolyte and a molten alkaline carbonate phase) exhibit promising performance due to the high electrolyte conductivity within the so-called intermediate temperature ranges (400-600 C). These electrolytes are a blend of those traditionally used in Solid Oxide and Molten Car...

High Performance C/S Composite Cathodes with Conventional Carbonate-Based Electrolytes in Li-S Battery

High stable C/S composites are fabricated by a novel high-temperature sulfur infusion into micro-mesoporous carbon method following with solvent cleaning treatment. The C/S composite cathodes show high Coulombic efficiency, long cycling stability and good rate capability in the electrolyte of 1.0 M LiPF6 + EC/DEC (1:1 v/v), for instance, the reversible capacity of the treated C/S-50 (50% S) cat...

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...
