The innovation process describes the process and results for fabrication of a magnetron sputter deposited fully dense electrolyte layer (8YSZ/GDC/LSGM) embedded in a high performance membrane electrolyte assembly (MEA) (Unit Cell) of Solid Oxide Fuel Cell. A single cell with airtight electrolyte layer (8YSZ/GDC/LSGM) is prepared via thin film technique of magnetron sputter deposition, combined with SOFC-MEA processing methods (such as tape casting, lamination, vacuum hot pressing, screen printing, spin coating, and plasma spray coating) and sintering optimization conditions. The gas permeability of the electrolyte layer is below 1&#xd7;10L/cm/sec and the open circuit voltage/power density of the single cell performance test exceeds 1.0 V and 500 mW/cm.

The present invention provides a high capacity hydrogen storage material in which a plural mesopore channels and fractal networks of nanopore channels communicating therewith and connecting to the micropores are formed in a microporous material, wherein a plural metal particles are formed on the surface of the mesopore and nanopore channels and of the micropores. In another embodiment, the present invention also provides a method for making the hydrogen storage material through oxidizing the microporous material so as to form a plural mesopore channels and fractal networks of nanopore channels, both of which are connected to the micropores to form a base for the deposition of metal particles capable of decomposing hydrogen molecules into hydrogen atoms. The high capacity hydrogen storage material is capable of increasing the capacity of hydrogen storage, and besides, the oxidizing process for making the hydrogen storage material is simple and has merits of saving cost.

This invention describes the process for fabrication of a high conductivity and low resistance solid oxide fuel cell. An anode substrate is mainly prepared via tape casting technique and modified by abrasion and polish process. Electrolyte is fabricated onto the polished side by thin film technologies and can attach well in the cross section. Grinding surface of anode side about 10-30 &#x3bc;um after finish of MEA combination can get a high conductivity and low resistance unit cell and enhance cell performance effectively.
