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 کاملSimulation of a Solid Oxide Fuel Cell with External Steam Methane Reforming and Bypass
Fuel flexibility is a significant advantage of solid oxide fuel cells (SOFCs) and can be attributed to their high operating temperature. The eligibility of a combined heat and power (CHP) system has been investigated as a new power generation methode, in this study. Natural gas fueled SOFC power systems via methane steam reforming (MSR) yield electrical conversion efficiencies exceeding 50% and...
متن کاملElectrolyte Degradation in Anode Supported Microtubular YSZ-based Solid Oxide Steam Electrolysis Cells at high voltages of operation
Degradation of solid oxide electrolysis cells (SOECs) is probably the biggest concern in the field of high temperature steam electrolysis (HTSE). Anode supported, YSZ-based microtubular solid oxide fuel cells (SOFC) have been tested in fuel cell mode and also at high voltages (up to 2.8V) under electrolysis mode. At high steam conversion rates the cell voltage tends to saturate. Our hypothesis ...

*Correspondence: Victor M. Orera, CSIC-Universidad de Zaragoza, C/Pedro Cerbuna 10, Zaragoza 50009, Spain e-mail: [email protected] Higher energetic density, better resistance to thermal stresses, and smaller starting times as compared with conventional planar stacks, make the so-called microtubular SOFC (mT-SOFCs with diameters in the millimeter size region) devices suitable for portable applica...
متن کاملIV.A.3 A Reversible Planar Solid Oxide Fuel-Fed Electrolysis Cell and Solid Oxide Fuel Cell for Hydrogen and Electricity Production Operating on Natural Gas/Biogas
Objectives • Develop the concept of a solid oxide fuel-fed electrolysis cell (SOFEC) for hydrogen production. • Identify and develop SOFEC cathode materials that are electrocatalytically and chemically stable in both reducing and oxidizing atmospheres. • Develop a novel concept of a composite/hybrid planar SOFEC-solid oxide fuel cell (SOFC) stack to co-generate hydrogen and electricity. • Demon...
