Title:
連続螺旋転位成長によるナノ構造の層の生成
Document Type and Number:
Japanese Patent JP5107925
Kind Code:
B2
Abstract:
Processes for extending the length of nanostructured support elements of thin film layers are described. The processes involve the initial formation nanostructured support elements during a first annealing step. A coating of material is deposited on the nanostructured support elements. During a second annealing step the initially formed nanostructured support elements longitudinally extend. Longer nanostructured support elements provide increased surface area for supporting catalyst material, thus allowing higher catalyst loading across the layer. Layers having extended nanostructured support elements are particularly useful for electrochemical devices such as fuel cells where catalyst activity is related to the surface area available to support the catalyst.
