An Fe group ternary nanoalloy (NA) catalyst enabled selective electrocatalysis towards CO2-free power generation from highly deliverable ethylene glycol (EG). A solid-solution-type FeCoNi NA catalyst supported on carbon was prepared by a two-step reduction method. High-resolution electron microscopy techniques identified atomic-level mixing of constituent elements in the nanoalloy. We examined ...

in this work, the strontium-doped lanthanum manganite- a ceramic material- used as cathode in solid oxide fuel cells. an impression of grinding time on the structural and thermal properties of sr-doped lamno3 system with la1-xsrxmno3 (x=0.2) stoichiometric ratio was investigated. the nano crystallite lsm powder with cubic structure was prepared by varying the milling time of planetary monomill ...

protective coatings that resist oxide scale growth and decrease chromium evaporation are necessary to makestainless steel interconnect materials for long-term durable operation of solid oxide fuel cells (sofcs). inthis study a layer of manganese was coated on the surface of aisi 441 ferritic stainless steel which is used insolid oxide fuel cells for interconnect applications. the oxidation beha...

an efficient procedure is presented for the evaluation of solid oxide fuel cell (sofc) anode microstructure triple phase boundary length (tpbl). triple phase boundary- the one that is common between three phases of the microstructure- has a great influence on the overall efficiency of sofc because all electrochemical reactions of anode take place in its vicinity. therefore, evaluation of tpbl f...

In present research work, anion exchange membranes based on quaternized polysulfone with ammonium cation moieties (QAPSF) were prepared by chloromethylation, amination and alkalization. The chloromethylated polysulfone were characterized by 1HNMR spectroscopy and functionalization degree was determined according to peak area integration. Ion transport properties (ionic conductivity, ion exchang...

In present research work, homogeneous anion exchange membranes based on polysulfone (QAPSFs) were prepared via chloromethylation, amination and alkalization. In amination step, trimethylamine and N,N,N',N'-tetramethyl-1,6-hexanediamine were used as amination and crosslinking agents, respectively. The chloromethylated polysulfone was characterized by 1HNMR spectroscopy and chloromethylation degr...

A novel, physically strong, quaternary-ammonium-functionalised radiation-grafted ETFE alkaline anion-exchange membrane (AAEM) has been developed for application in fuel cells without undesirable addition of MOH into the anode fuel stream, thereby facilitating stable performances and long term operational lifetimes. A promising H2/O2 fuel cell peak power performance of 130 mW cm -2 was obtained ...

The realm of alkaline-based fuel cells has with the arrival anionic exchange membrane (AEMFCs) taken a great step to replace traditional liquid electrolyte alkaline (AFCs). following review summarises progress, bottleneck issues and highlights most recent research trends within field. activity catalyst materials greatly advanced, however achieving long-term stability remains challenge. Great AE...

long–term stability and oxidation resistance of aisi 439 ferritic stainless steel used as interconnects in solid oxide fuel cells can be improved by use of a protective coating. in this study the pack cementation method was employed to coat aisi 439 ferritic stainless steel with manganese. isothermal oxidation was conducted at 800 ºc for 200 hours in static air to investigate the role of coatin...
