The present disclosure belongs to the technical field of solid oxide fuel cell stacks, and particularly relates to a method for preparing a connector-free anode-supported solid oxide fuel cell stack by means of 3D printing. The method includes taking a mixed paste of an anode ceramic powder and a photosensitive resin as a raw material, and preparing a three-dimensional channel honeycomb-type anode-supported matrix by means of 3D printing; and obtaining an anode-supported solid oxide fuel cell by means of an impregnation method, effectively bringing same into contact, and abutting and sealing same in the order of a cathode, an anode and a cathode, and forming the connector-free anode-supported solid oxide fuel cell stack after performing connection in series.

A lithium battery and method for fabricating the same are provided herein. The battery cathode comprises a carbon structure filled with a catalyst, such as palladium-catalyst-filled carbon nanotubes (CNTs). The carbon structure provides a barrier between the catalyst and the electrolyte providing an increased stability of the electrolyte during both discharging and charging of a battery.

Solid oxide fuel cells that include an alumina substrate as support are described. The alumina substrate supported SOFCs can exhibit desirable electrochemical characteristics including high performance at intermediate temperatures and excellent thermal stability. The alumina substrate support is formed according to a modified phase-inversion process that forms a series of aligned micro-channels extending from a first side to a second opposite side of the support enabling gas distribution between an electrode (e.g., an anode) located on one side of the alumina substrate and the other, opposite side of the alumina substrate.
