摘要: Ni-based alloys were prepared by using the oxalate method and subsequent in-situ reduction. The crystallographic phase microstructure of catalysts investigated. These bimetallic mixed with gadolinium-doped ceria in order to obtain a composite material electronic-ionic conductivity. Catalytic electrocatalytic properties materials for conversion ethanol Electrochemical tests carried out utilizing alloy/CGO cermet as barrier layer conventional anode-supported solid oxide fuel cell (SOFC). A comparative study between modified cells SOFC without protective was made. aim efficiently convert directly into electricity or syngas (H2 CO) just before anode support. In accordance ex-situ catalytic tests, Ni–Co/CGO showed superior performance towards direct utilization dry than bare that Ni–Cu/CGO. peak power 550 mW cm−2 achieved ethanol-fed pre-layer modified-cell at 800 °C. total low frequency resistance <0.5 Ω cm2 0.8 V voltage recorded presence fed SOFC.
