Solid oxygen fuel cell. For decades experts have considered solid oxide fuel cells SOFCs to hold the greatest potential of any fuel cell technology due to their extremely high electrical efficiencies and low operating costs. In fact SOFCs are likely to emerge as the. Solid oxide fuel cells SOFCs offer a stable and efficient way to generate clean electrochemical power but are impractical for use in portable devices because of.
Solid Oxide fuel cells SOFC use a hard ceramic compound of metal like calcium or zirconium oxides chemically O 2 as electrolyte. Efficiency is about 60 percent and operating temperatures are about 1000 C about 1800 F. Cells output is up to 100 kW.
At such high temperatures a reformer is not required to extract hydrogen from the fuel and waste heat can be recycled to make additional.

Kevin Huang John B. Goodenough in Solid Oxide Fuel Cell Technology 2009. The degradation of SOFC performance is often found to be associated with various mechanisms of electrode poisoning.
Good examples include the presence of trace sulfur in the fuel stream that can lead to deterioration of the anode performance and gas-phase chromium oxide in the air stream that can. Intermediate temperature solid oxide fuel cells ITSOFCs are costeffective and efficient energy conversion systems. The sluggish oxygen reduction reaction ORR and the degradation of cathodes are critical challenges to the commercialization of ITSOFCs.
A fuel cell is a galvanic cell also called an electrochemical cell The relation between the chemical energy Δ G Gibbs free energy of reaction of a cell reaction and the equilibrium ideal electrical voltage also called the electromotive force Emf of the cell is given by -Δ G n F Emf. A solid oxide fuel cell SOFC is an electrochemical device that converts the chemical energy in fuels into electrical energy by utilizing the natural tendency of oxygen and hydrogen to react1 Fuel cells are able to convert hydrogen-based fuels with higher efficiency compared to. Solid oxide fuel cells are one of the many types of fuel cells and produce electricity water heat and small amounts of carbon dioxide using natural gas as the fuel.
How does a solid oxide fuel cell work. Electricity is the movement of electrons and all elements hydrogen oxygen and others have varying numbers of electrons. Direct Operation of Solid Oxide Fuel Cells on Low-Concentration Oxygen-Bearing Coal-Bed Methane with High Stability Energy Fuels This paper studies the electrochemical feasibility of the direct conversion of low-concentration oxygen-bearing coal-bed methane CBM 30 vol CH4 to electricity via solid oxide fuel cells SOFCs.
Solid oxide fuel cells SOFCs are the most efficient devices yet invented for conversion of chemical fuels directly into electrical power 1. They consist of a solid dense ceramic electrolyte placed between two porous electrodes. The fuel is supplied to the anode side air or oxygen to the cathode.
The shown cell is mechanically supported by a thick solid oxygen ion conductive yttrium stabilized zirconium dioxide YSZ electrolyte electrolyte supported cell ESC. Another option is to support the cell by a thick porous fuel electrode substrate anode supported cell ASC or by a porous metal substrate metal supported cell MSC. Paradigmatic examples include solid-oxide fuel cells gas sensors and electrochemical pumps that operate by directing and controlling vacancy.
