Internal reforming of methane in solid oxide fuel cell systems

Direct Utilization of Liquid Fuels in SOFC for Portable Applications: Challenges for the Selection of Alternative Anodes

“…The presence of temperature gradients and coking are the main limitations for DIR-SOFC. Research on direct internal reforming SOFC with Ni/YSZ anode is limited almost exclusively to methane [17][18][19][20][21][22][23], with few examples of IIR-SOFC using model fuels [24][25][26].…”

Advanced Power Generation Technologies: Fuel Cells

“…However, only a few experimental and modeling works, such as Finnerty et al (2000) and Petruzzi et al (2003), used POX and great majority of the SOFC systems in the literature applied the steam reformer. It is suggested that, for small units, where compactness is important, POX process is applied and for applications, where high efficiency is desired, steam reformer is used (Peters et al 2002). Also, POX is used when the fuel cell is fueled with liquid fuel, for example, for auxiliary power units (APUs) in vehicles, where the system should use same fuel as the vehicle to avoid a second fuel tank (Petruzzi et al 2003;Steffen et al, 2005).…”

“…Existence of heavier hydrocarbons in natural gas, which at high temperatures have a tendency to produce unwanted materials, such as carbon, can intensify the problem. Therefore, to avoid aforementioned problems, it is suggested that the fuel cell system to be equipped with a compact pre-reformer (Peters et al, 2000(Peters et al, , 2002Ahmed & Foger, 2000;Calise et al, 2007;Dicks et al, 2000).…”

Alumina Supported Iron Catalyst for Hydrogen Production: Calcination Study

“…INTRODUCTION ELCOME Hydrogen, a clean energy fuel, can be taken as a demanding alternative to conventional fossil fuels in order to reduce CO 2 emissions [1][2][3]. Fossil fuels are generally accepted as a source for hydrogen production in the near future.…”
