Au/La1−xSrxMnO3 nanocomposite for chemical-energy cogeneration in solid oxide fuel cell reactor

“…Total pore volume (cm 3 performance in which these results support the previous finding [18]. As a result from this work, Au/LSM is a potential anode catalyst for further application in SOFC-type reactor for the cogeneration of chemicals and electricity.…”

“…A solid oxide fuel cell (SOFC) is one of the most attractive fuel cells which produce electricity directly from a fuel with high conversion efficiency, fuel flexibility and low emissions. The use of SOFC reactor for co-generation of C 2 hydrocarbons and electrical power was first reported by Pujare and Sammells [3], in which a high selectivity to C 2 hydrocarbons (>90%) was achieved but with low conversion. Although an SOFC type reactor is more attractive than other conventional reactors due to an achievement of high selectivity and possible use in electricity generation, there are still not many studies on this subject.…”

Development of Au/La1−xSrxMnO3 nanocomposites for further application in a solid oxide fuel cell type reactor

“…However, there has been some research focusing on applications of SOFCs for the cogeneration of chemicals and electrical power. Various reaction systems have been tested, including styrene production from ethylbenzene [1], partial oxidation of methane (POM) to synthesis gas [2][3][4] and oxidative coupling of methane (OCM) to C 2 hydrocarbons (ethane and ethylene) [5]. The effective catalytic conversion of methane into more useful and valuable products (such as H 2 , syngas and C 2 hydrocarbons) with sufficiently high yields, selectivity and stability remains a great challenge.…”

Reviews on Fuel Cell Technology for Valuable Chemicals and Energy Co-Generation

“…For instance, Solid oxide fuel cell system with membrane reactor is investigated, which anode electrode is LaAlO and cathode is LSM. When electrochemical reaction occurred, oxygen ion transferred from cathode cell to anode cell by equation 8and 9Cathode: 22…”

“…Pujare and Sammells [22] investigatedthe oxidative coupling of methane with SOFC. High C 2 hydrocarbon selectivity ( 90%) was observed, although the methane conversion was relatively low.…”
