Article
Porous buffer layers for anode-supported solid oxide fuel cells (SOFCs) have been investigated for many years with different thicknesses of the buffer layer in each study. In this work, micro-tubular SOFCs having samarium-doped ceria (SDC) and gadolinium-doped ceria (GDC) buffer layers are compared using the current-voltage technique, electrochemic...
Article
Owing to several unsuccessful attempts of integrating dual chambered solid oxide fuel cell stack with the auxiliary power unit (APU) gas turbine, a novel concept for integration of flame-assisted fuel cells (FFC) with the gas turbine of an APU is presented in this paper. A complete analytical model of the FFC integrated hybrid system is presented....
Article
Thermal partial oxidation, or fuel-rich combustion, is a non-catalytic option for reforming hydrocarbons to synthesis gas for direct conversion in micro-Tubular Solid Oxide Fuel Cells (SOFCs). A number of studies have demonstrated the potential of using heat recirculation to sustain combustion at high equivalence ratios, where the concentration of...
Article
Solid Oxide Fuel Cells (SOFCs) offer advantages for micro-Combined Heat and Power (μCHP), but currently suffer from slow startup (>1 h) and limited thermal cycling which reduces the applications, energy savings and economics. In this work, a micro-Tubular SOFC stack is integrated into a residential furnace to create a micro-Tubular Flame-assisted F...

Flame-assisted fuel cell (FFC) systems have been investigated and developed for small scale power generation applications. The introduction of micro-combustion into the FFC setup has potential to increase the electrical efficiency of the system and reduce the size. However, micro-combustion at high equivalence ratios in FFC systems still needs more...

Flame-assisted fuel cell (FFC) studies have been limited to lower fuel-rich equivalence ratios (∼1–1.7, due to the upper flammability limit and sooting limit) where only small concentrations of H2 and CO can be generated in the exhaust. In this work, a non-catalytic microcombustion based FFC is proposed for direct use of hydrocarbons for power gene...
Article
Solid oxide fuel cell research and development has faced challenges with slow startup, slow shutdown and a limited number of thermal cycles, which hinders the technology in areas like micro-combined heat and power. A novel micro combined heat and power system, based on a boiler/hot water heater with integrated micro-tubular flame assisted fuel cell...
Conference Paper
Direct use of propane and butane in Solid Oxide Fuel Cells (SOFCs) is desirable due to the availability of the fuel source, but is challenging due to carbon coking, particularly on the commercially available Ni+YSZ anode.

The performance of anode-supported solid oxide fuel cells was investigated as the SDC buffer layer thickness was varied between ∼0.4 μm and ∼2.3 μm. 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−2 was achieved at 800 °C and an...

Fuel cell technology continues to advance and is being deployed worldwide in many applications. To date, successful applications have included transportation applications such as vehicles, stationary power such as micro-combined heat and power, and a range of portable power applications. While the use of hydrogen fuel has been established, direct operation with hydrocarbons is an ongoing research topic. Hydrocarbons fuels are readily available and, if deployed directly in fuel cells, can result in more efficient power generation and lower emissions than conventional heat engines. Many approaches have been explored for the direct use of hydrocarbons in fuel cell applications, including novel system designs as well as catalyst and material development. System design includes ongoing research in partial oxidation reformers, steam reformers, water gas shift reactors, direct flame fuel cells, and flame-assisted fuel cells, among others. This Special Issue is focused on advances in the direct use of hydrocarbons for fuel cell applications. Deadline for manuscript submissions: 30 April 2021. Keywords: solid oxide fuel cell (SOFC), polymer electrolyte membrane fuel cell (PEMFC), fuel cells, partial oxidation, syngas generation, advanced combustion process, direct hydrocarbon energy conversion
