High power-density single-chamber fuel cells operated on methane
Single-chamber solid oxide fuel cells (SC-SOFCs) incorporating thin-film Sm0.15Ce0.85O1.925 (SDC) as the electrolyte, thick Ni + SDC as the (supporting) anode and SDC + BSCF (Ba0.5Sr0.5Co0.8Fe0.2O3−δ) as the cathode were operated in a mixture of methane, oxygen and helium at furnace temperatures of 500–650 ◦C. Because of the exothermic nature of the oxidation reactions that occur at the anode, ...
متن کاملCatalytic and Non-catalytic Conversion of Methane to C2 Hydrocarbons in a Low Temperature Plasma
The direct conversion of methane to C2 hydrocarbons, in a quartz tube reactor enforced by a DC corona discharge, was investigated at atmospheric pressure. The process was carried out in the presence of metal oxide catalysts of Mn/W/SiO2, Mn/W/SiO2 (tetraethyl orthosilicate, TEOS), and Mn/W/CNT (supported on carbon nanotubes). The total yield to C2 hydrocarbons in the presence of metal oxide cat...
متن کاملQuantifying Low Temperature Production of Methane on Mars
Introduction: Methane was first detected in the Matian atmosphere in 2003 [1-3], and its implications have been widely debated [e.g., 4-8]. Methane can be generated in terrestrial biological systems, and so is a potential indicator for past or present life (see e.g., [4,5]). However, methane can be produced anorganically (without intervention of life) in several sorts of terrestrial environment...
متن کاملAnaerobic methane oxidation in low-organic content methane seep sediments
Sulfate-dependent anaerobic oxidation of methane (AOM) is the key sedimentary microbial process limiting methane emissions from marine sediments and methane seeps. In this study, we investigate how the presence of low-organic content sediment influences the capacity and efficiency of AOM at Bullseye vent, a gas hydrate-bearing cold seep offshore of Vancouver Island, Canada. The upper 8 m of sed...
متن کاملDesign of new materials for methane storage.
One of the strategic goals of the modern automobile manufacturing industry is to replace gasoline and diesel with alternative fuels such as natural gas. In this report, we elucidate the desired characteristics of an optimal adsorbent for gas storage. The U.S. Department of Energy has outlined several requirements that adsorbents must fulfill for natural gas to become economically viable, with a...
