The effects of methane concentration and current load cycle on the performance and durability of integrated planar solid oxide fuel cell (IP‐SOFC) obtained from Rolls Royce Fuel Cell Systems Ltd (RRFCS) has been investigated. A Support Layer for Solid Oxide Fuel Cells. Commercial application of these devices, however, requires further improvements in their performance and stability. N2 - Solid oxide fuel cells (SOFCs) with thin yttria-stabilized zirconia (YSZ) electrolytes on porous Ni-YSZ anodes were successfully operated with humidified methane and natural gas. While these materials show great promise, scale up of protonic-ceramic fuel cells beyond the “button-cell” level remains limited. 1 Background of Solid Oxide Fuel Cells The high operating temperature of solid oxide fuel cells (SOFCs) o ers advantages and disadvantages compared with low temperature fuel cells such as polymer electrolyte.

PSOFC is defined as Pressurized Solid Oxide Fuel Cell rarely. The focus of this dissertation is the development of a Solid Oxide Fuel Cell (SOFC) that can operate with hydrocarbon fuels without the need for pre-reforming. Rather, the efficiency of the fuel cell based power plant can be increased to about 70% when coupled with a gas turbine. Mechanical, Maritime and Materials Engineering. It is also important for fuel cell technology to achieve efficient electrode operation with different hydrocarbon fuels 3,4 , although such fuels are more demanding than pure hydrogen. Author: Vincenzo Liso, Giovanni Cinti, Mads Pagh Nielsen, Umberto Desideri. A reformer is not necessary to extract hydrogen from the fuel, but the sulfur needs to be removed before it can be used. Solid Oxide Fuel Cells S olid oxide fuel cells (SOFCs) offer a clean, low-pollution technology to electrochemically generate electricity at high efficiencies; since their efficiencies are not limited by the Carnot cycle of a heat engine. Furthermore, the waste heat generated from the cell can also be used to heat the home, which increases the energy efficiency [13]. Compared to other fuel cell technologies, solid oxide fuel cell (SOFC) based systems are better suited to meeting NASA's efficiency targets while operating directly on methane and oxygen reactants. Carbon deposition on a Ni‐based anode is troublesome for the direct power generation from methane‐based fuels using solid oxide fuel cell. 27 W/cm2 at 800 °C were observed. Overview Methane Ethane Diesel Gasoline Coal gas. SOFC is highly efficient and require no external reformer as it directly converts hydrocarbon fuel to electrical energy. In August, Franklin Fuel Cell reported a successful test of Solid-Oxide Fuel Cell (SOFC) technology on 16 different types of fuels, including propane, methane, ethanol, natural gas, and diesel. Hedengren. Operation of Anode-Supported Solid Oxide Fuel Cells on Methane and Natural Gas Article (PDF Available) in Solid State Ionics 158(1-2):11-16 · February 2003 with 240 Reads How we measure 'reads'. The electricity costs for a mass manufactured solid oxide fuel cell could be competitive with centralized power production plants with costs estimated to be in the $0. Hedengren, and Thomas F. Direct CH4-fueled solid oxide fuel cells (SOFCs) have been studied for a few decades, but carbon depositions on the Ni-based anodes are still remained as a major problem. 52 W/cm2 at 700 °C and 1. 6 V, How Much Fuel Cell Active Area (in Cm2) Would Be Required To Deliver 3 KW Of Electrical Power?. title = "Direct operation of solid oxide fuel cells with methane fuel", abstract = "The operation of Ni-YSZ anode supported SOFCs on methane fuel is described. Modeling and Parametric Simulations of Solid Oxide Fuel Cells with Methane Carbon Dioxide Reforming Meng Ni* Building Energy Research Group, Department of Building and Real Estate The Hong Kong Polytechnic University, Hung Hom, Kowloon, Hong Kong, China Abstract: A two-dimensional model is developed to simulate the performance of solid oxide. Contributor. These cells could use natural gas—which is mostly made up of methane—directly. Colonna, Modeling of solid oxide fuel cells for dynamic simulations of integrated systems, Applied Thermal Engineering (2009), doi: 10. Fuel Cell system. A calcium-doped ceria with nominal compositions of Ce 1-x Ca x O 2-δ (0. Performance degradation caused by carbon deposition substantially restricts the development of direct methane solid oxide fuel cells (SOFCs). 1-supported solid oxide fuel cells are fabricated by tape casting-screen printing-sintering process; and the activity for CH 4 reforming and electrochemical performance are examined with wet (3 vol.

Molten Carbonate Fuel Cell (MCFC); 5. Thermodynamic modeling and performance of advanced solid oxide fuel cells. Solid oxide fuel cell Xiaoyong's research interests include direct carbon fuel cells, direct methane fuel cell and solid oxide fuel cells with strong application focus on clean energy and environment. These fuel cells are small and quiet enough for household use, unlike combustion turbines. -The Design of Connection Solid Oxide Fuel Cell (SOFC) Integrated Grid with Three-Phase Inverter. Title: Solid oxide fuel cell performance comparison fuelled by methane, MeOH, EtOH and gasoline surrogate C 8 H 18. H2, natural gas) and oxidant (e. This performance is comparable to that of fuel. It is also important for fuel cell technology to achieve efficient electrode operation with different hydrocarbon fuels 3,4 , although such fuels are more demanding than pure hydrogen. Zhang, et al. Hedengren, and Thomas F. A number of different fuel cells have been under development for stationary, transport and portable power applications. Solid Oxide Fuel Cell (SOFC) development and manufacturing technologies. , in the form of air 24 as labelled in FIG. Hydrogen is the best fuel for powering fuel cells, but its cost is exorbitant. Researchers developed a low-temperature direct methane fuel cell in 1962, and Andrew M. The Fuel Cell Produces Only Carbon Dioxide And Water As A By-product. for power plants (300 MW el) or as combined heat and power generation the solid oxide fuel cell (SOFC) is generally preferred. Rather, the efficiency of the fuel cell based power plant can be increased to about 70% when coupled with a gas turbine.
