Structure degradation and redistribution of alloying elements in austenitic steel of current collectors of solid oxide fuel cells in service

The Physics of Metals and Metallography, 2013
The degradation of the 10Kh23N18 steel structure with and without a protective Mn-Co-spinel coating after 8800 h of operation at 950°C is investigated as a switchgear material of a solid oxide fuel cell. Structural studies have shown no significant differences in the redistribution of alloying elements, in the composition and structure of oxide layers ...

Investigation Into Mechanical Behavior of the Current Collector for the Molten Carbonate Fuel Cell Through Finite Element Analysis Using Hexahedral Mesh Coarsening

Journal of Fuel Cell Science and Technology, 2014
The current collector for the molten carbonate fuel cell (MCFC), which is a repeated structure of sheared protrusions, is manufactured from the three-stage forming process. For the precise and efficient simulation of the mechanical behavior of the current collector, the results of the forming process such as the deformed geometry and the distribution ...

Chemical/Electrochemical Dual‐Driven Transition Behavior of Copper Element from Current Collector to Chalcogenide Anode in Sodium‐Ion Batteries

Advanced Functional Materials
AbstractThe transition phenomenon involving copper replacing the transition metal elements within transition metal chalcogenides (TMCs) is a recent and unique observation in the context of sodium ion batteries (SIBs) where TMCs serve as anodes. Fundamental understanding of the driving forces and kinetics governing this transition is crucial for ...

Light element (B, N) co-doped graphitic films on copper as highly robust current collectors for anode-free Li metal battery applications

Applied Physics Reviews
We have examined the case of light atom (B, N) doped and co-doped graphitic films grown on copper for the anode-free Li Metal Battery (AFLMB) application. For nitrogen doping, the depositions were carried out by laser ablating pure graphite (Gr) in the presence of Nitrogen (N2) or Ammonia (NH3). In another interesting case, 5 wt.
