Steam Electrolysis Using a Microtubular Solid Oxide Fuel Cell
Reversible operation of a microtubular solid oxide fuel cell SOFC with high electrochemical efficiency is reported. These devices can ideally produce hydrogen from electricity and steam solid oxide electrolyser SOE and then use the stored hydrogen to generate electricity and heat SOFC , acting as a storage device for the electrical energy. A fuel-electrode-supported Ni–yttriastabilized zirconia...
متن کاملMicro-Solid Oxide Fuel Cell: A multi-fuel approach for portable applications
The impact of oxygen ion transport at the electrolyte–electrode interface of a micro-solid oxide fuel cell using different fuels is investigated. Model validation is performed to verify the results versus the reported values. Furthermore, as the hydrogen-to-carbon ratio decreases, the diffusivity of the oxygen ion increases. This increase in diffusivity is observed because the number of hydroge...
متن کاملRedox Stable Anodes for Solid Oxide Fuel Cells
*Correspondence: Fanglin Chen, Department of Mechanical Engineering, University of South Carolina, 300 Main Street, Columbia, SC 29208, USA e-mail: [email protected] Solid oxide fuel cells (SOFCs) can convert chemical energy from the fuel directly to electrical energy with high efficiency and fuel flexibility. Ni-based cermets have been the most widely adopted anode for SOFCs. However, the conv...
متن کاملPore Former Addition in the Preparation of Highly Porous Anode Using Phase-inversion Technique for Solid Oxide Fuel Cell
A detailed study on the anode structure of solid oxide fuel cell (SOFC) is very crucial in developing high performance power generating devices, given how porous electrodes are known to provide a number of active sites for reaction, consequently accelerate fuel conversion. This present study investigates the feasibility of pore former addition to nickel oxideyttria stabilized zirconia (NiO-YSZ)...
متن کاملPerformance and Aging of Microtubular YSZ-based Solid Oxide Regenerative Fuel Cells
Fuel electrode supported microtubular solid oxide fuel cells (SOFC) fabricated at ICMA have been characterized in both solid oxide steam electrolyser (SOEC) and fuel cell modes. The cells consists of a fuel electrode supporting tube of Ni/YSZ with 40% porosity, 400 μm thickness, 2.4 mm diameter and 100-150 mm length, a 15 m thick YSZ electrolyte and a 50vol% LSM/YSZ composite air electrode of...
