Compact hydrogen production systems for solid polymer fuel cells

Catalytic steam reforming of methane, methanol, and ethanol over Ni/YSZ: The possible use of these fuels in internal reforming SOFC

“…methanol and ethanol) should be also possible when operated as an internal or in-stack reforming. Methanol is favorable due to its ready availability, high-specific energy and storage transportation convenience [8,9], while ethanol is also a promising candidate, since it is readily produced from renewable resources (e.g., fermentation of biomasses) and has reasonably high hydrogen content [10,11]. Douvartzides et al [12] applied a thermodynamic analysis to evaluate the feasibility of different fuels, i.e.…”

Hydrogen Production From Palmitic Acid Through Autothermal Reforming: Thermodynamic Analysis

“…Molar feed ratios of steam to palmitic acid (S/C) and oxygen to palmitic acid (O/C) are 0.5 to 4, respectively, with autothermal reaction at ambient pressure and temperatures between 800-1000°C. Methanation of CO synthesis is a catalytic exothermal process at temperatures of 473-673 K (200-400°C) and high pressure does not have any effect on hydrogen and carbon monoxide yields [13][14][15][16][17]. Hydrogen yield was calculated using Eq.…”

Organic/Inorganic Nanocomposite Membranes Development for Low Temperature Fuel Cell Applications

“…Methanol is a leading candidate to provide the hydrogen necessary to power a fuel cell, especially in vehicular applications (Ledjeff-Hey et al, 1998;Mokrani & Scurrell, 2009;Olah et al, 2009). Methanol is currently used as a feed stock for a variety of widely used organic chemicals, including formaldehyde, acetic acid, chloromethane, and methyl tert-butyl ether (MTBE).…”
