Integration of solid oxide fuel cell (SOFC) in coal gasification power plant technology would be one of the most promising technology in the coal utilization for power generation. The clean syngas from gas cleanup unit serves as fuel for SOFC in integrated gasification fuel cell power plant. The...

Trigeneration, which is able to provide cooling, heating and power, has been advocated to be a sustainable solution for building use in the urban area. With the high-temperature feature and maintenance convenience, solid oxide fuel cell (SOFC) becomes a promising prime mover of trigeneration. In...

We present exergy and economic analyses for two potential advanced coal-based power plants with CO2 capture and sequestration. Each system generates three products: electricity, carbon dioxide compressed to 15MPa, and pre-calcined feedstock for cement kilns. First, we analyzed a system that...

High temperature fuel cells are a promising technology for ultra-low emission power generation. This paper presents a novel poly-generating system capable of greater than 80% (LHV CH4) co-production efficiency with carbon capture and liquefaction. The proposed system synergistically integrates...

Temperature distribution over a Solid oxide fuel cell (SOFC) surface is a crucial parameter for design of a SOFC stack. The selection of both materials and the operating point of a stack is heavily affected by temperature gradient. Temperature distribution can also be used for control and...

In this study, the balance of plant (BOP) of an ethanol-fueled SOFC is analyzed using the GCTool software package developed by Argonne National Laboratory (ANL). The effects of the excess air ratio and fuel utilization on the electric and heat efficiencies of the SOFC are systematically examined...

For Solid Oxide Fuel Cells (SOFCs) to become an economically attractive energy conversion technology suitable materials which allow operation at lower temperatures, while retaining cell performance, must be developed. At the same time, the cell components must be inexpensive – requiring both...

In order to research the failure mechanism of Solid Oxide Fuel Cell (SOFC), an unsteady state two-dimensional model that considers the carbon deposition is presented. Navier–Stokes (N–S) equations, heat transfer equation, mass transfer equation, electron and ion transport equation are solved...

We present exergy and economic analyses of two advanced fossil fuel power plants configurations: an integrated gasification combined cycle with advanced H2 and O2 membrane separation including CO2 sequestration (Adv. IGCC–CCS) and an integrated gasification fuel cell cycle with a catalytic...

In this study, the main sections required to produce electricity in an SOFC short stack starting from biogas were studied and tested at a lab-scale level. A test-rig including a cleaning unit, a reformer and an SOFC stack was built and used to run a test of 500h. In the plant, an in-house planar...
