  1. Xingbo Liu West Virginia University September 23, 2013 Center of Electrochemical Energy Systems (CEES) in WVU

  2. High Efficiency • Fuel Flexibility & Impurity Tolerance • Internal Reforming Capability

  3. SOFC in Integrated Gasification Fuel-cell Combined Cycle (IGFC) System

  4. SOFC and Coal Syngas • Syngas: Product of coal gasification • Typical Compositions: 30% H2, 26% H2O, 23% CO, 21% CO2. Intentionally control the water concentration to prevent carbon deposition (coking) on the anode surface. • Contaminants: H2S, HCl, PH3, AsH3, Hg, Sb, Zn, Cd, Se, HCl etc. They may react and destroy the cell anode. J.P. Trembly, R.S. Gemmen, D.J. Bayless Journal of Power Sources 163 (2007) 986–996 • In coal syngas PH3 concentration is typically 1-10 ppm. Mingyang Gong, Xingbo Liu*, Jason Trembly, Christopher Johnson: “Sulfur-tolerant anode materials for solid oxide fuel cell application”, Journal of Power Sources 168 (2007) 289-298

  5. Challenges in Coal-Based SOFC Systems • Anode • Impurity Effects on Ni-YSZ Anode (P, S, Cl, etc.) • Impurity Tolerant Anodes • Interconnect • Corrosion of Metallic Interconnect in Coal Syngas • Electrochemical Deposition of (Mn,Co) spinel coatings • Cathode • Improving Performance by Infiltration • Fundamental Parameters Characterization • ORR Modeling in Infiltrated Cathode

  6. Utilizing Shale Gas with SOFC • High Efficiency • Concurrent Generation of Power and Chemicals 6

  7. Launch of CEES

  8. First MW Na-S Battery in US, near Charleston, WV 50 m Wind Map in WV Energy Storage – A Game Changer • Fossil–Renewable“Hybrid”Grid • Peak Shaving, Power Quality • Community Energy Storage • Smart Grid AES Laurel Mountain Project near Elkins, WV

  9. Electrolyte Cathode Layer-by-Layer – Li Protective Layer Cell Modeling - Celik ab initio/Tight Binding - Lewis TEM - Song Manufacturing - Liu Anode Electrolyte Development - Liu Ionic liquid Synthesis - Shi + Cathode plate Cathode Seal ring Copper wool Gasket Anode: Sodium Anode plate NaSICON/glass electrolyte Planar Sodium-Batteries

  10. Summary • CEES is doing R&D on high temperature electrochemical systems for energy conversion and storage • Solid Oxide Fuel Cells • Sodium Batteries for Stationary Energy Storage • Etc. • The advantages of these systems are • Highly efficient • Multi-functional • Reduce Carbon footprint and other pollutions • Workforce development • Business Development and Job Creation in WV
