Currently the role of fuel cells in future power generation is being examined, tested and 7 discussed. However, implementing systems is more difficult because of sealing challenges, slow 8 start-up and complex thermal management and fuel processing. A novel furnace system with a 9 flame-assisted fuel cell is proposed that combines the thermal management and fuel processing 10 systems by utilizing fuel-rich combustion. In addition, the flame-assisted fuel cell furnace is a 11 micro-combined heat and power system, which can produce electricity for homes or businesses, 12 providing resilience during power disruption while still providing heat. A micro-tubular solid 13 oxide fuel cell achieves a significant performance of 430 mW cm-2 operating in a model fuel-rich 14 exhaust stream.
This report documents a series of time-averaged gas species measurements made along the centerline of methanol, ethanol, acetone, and methane pool fires steadily burning in a quiescent environment. All gas species measurements are obtained using a Gas Chromatograph/ Mass Spectrometer System (GC/MS) for gas samples extracted at various heights above the fire and repeated at least twice at each location. Gas species volume fractions are determined via the GC/MS using predetermined calibration factors. Soot mass fractions are simultaneously measured during the gas sampling process. The gas species volume and soot mass fractions are compared at different heights within the fire and across a variety of different fuels. Other fire parameters are measured as well, including time-averaged temperature measurements and mass burning rates.
Intermediate temperature solid oxide fuel cell Buffer layer Interlayer Anode-supported solid oxide fuel cell a b s t r a c tThe performance of anode-supported solid oxide fuel cells was investigated as the SDC buffer layer thickness was varied between~0.4 mm and~2.3 mm. The thickness of the buffer layer has a significant effect with the peak performance varying in magnitude by a factor of almost three. A peak power density of 1106 mW cm À2 was achieved at 800 C and an optimal SDC buffer layer thickness of~1.5 mm. The performance variation was complex due to a balance between ohmic and polarization losses, triple phase boundary area, pin holes and interfacial reactions between the BSCF þ SDC cathode, SDC buffer layer, and YSZ electrolyte. Understanding this variation is essential in order to compare two fuel cells having a different porous buffer layer thickness.
Experimental studies and characterization of the interfacial impedance of a novel solvent-casted solid polymer electrolyte (SPE) and Li1.3Al0.3Ti1.7(PO4)3 (LATP) ceramic bilayer electrolyte are conducted. Overall, resistance of the bilayer electrolyte decreased compared to single LATP ceramic electrolyte. The mechanism of the enhanced ion transportation at the interface is analyzed and discussed. Using the as-prepared multilayer electrolyte, all-solid-state lithium ion batteries (ASSLIBs) were fabricated with lithium metal as anode and LiMn2O4 (LMO) as cathode material. The charge/discharge properties and impedance of the cell at different temperatures were investigated. This work demonstrates the feasibility and potential of using a multilayer electrolyte structure for ASSLIBs with flexible geometries and dimensions for design.
Summary
This study documents a series of time‐averaged gas species measurements made along the centerline of a 30 cm methanol pool fire steadily burning in a quiescent environment. All gas species measurements were obtained using a gas chromatograph/mass spectrometer system (GC/MS). Measurements were made at different heights along the centerline of the fire and repeated at least twice for each location. Gas species volume fractions were determined via the GC/MS using predetermined calibration factors. The gas species volume fractions were compared at different heights within the methanol fire.
