    • PROBLEM TO BE SOLVED: To suppress aggregation between fibers in supporting an ionomer on a fiber surface of an array body in which carbon-containing fibers having a fiber outer diameter of less than 10 nm are arranged substantially in parallel.SOLUTION: There is provided a microstructure material including: an array body comprising a plurality of carbon-containing fibers having a fiber outer diameter of 0.4 nm or more and less than 10 nm while fiber axes of the carbon-containing fibers are arranged substantially in parallel; an ionomer in contact with side walls of the carbon-containing fibers; and a space where the carbon-containing fibers and the ionomer are not present. In the microstructure material, a summation of areas of regions where a distance between adjacent carbon-containing fibers is less than 1 μm in a given cross section substantially vertical to the fiber axis direction of the array body is larger than 20% of the total cross sectional area. A method for manufacturing the microstructure material, and a membrane-electrode assembly for a fuel cell, manufactured using the microstructure material are also provided.

    • PROBLEM TO BE SOLVED: To provide a substrate for CNT growth capable of continuously growing CNT with relatively long length and a method for manufacturing CNT. SOLUTION: The substrate 20 for CNT growth comprises an anodized alumina film 12 having gas permeability, a porous protection layer 16 having gas permeability and formed on the surface of the anodized alumina film 12, and a catalyst 14 for CNT growth deposited on the porous protection layer 16. The method of manufacturing CNT involves a growth step of supplying raw material gases containing a carbon source to the surface of the substrate 20 for CNT growth as described above and growing CNT 30 on the surface of the substrate 20 for CNT growth. The substrate for CNT growth is preferable to further comprise a porous base material 22 for supporting the anodized alumina film 12. Further, the growth step is preferable to supply the raw material gases toward the rear face from the deposition face of the catalyst 14 for CNT growth in the substrate 20 for CNT growth.
