CARBON FIBER, POROUS SUPPORT-CARBON FIBER COMPOSITE AND METHOD FOR PRODUCING THE SAME AS WELL AS CATALYST STRUCTURE, ELECTRODE FOR SOLID POLYMER FUEL CELL AND SOLID POLYMER FUEL CELL

摘要

This invention relates to a method for producing carbon fibers having a sufficiently small fiber diameter, and more particularly to (1) a method for producing carbon fibers, which comprising the steps of jetting a polymer material-containing solution by an electrospinning method to form a deposit layer of a fibrous substance comprising the polymer material and firing the deposit layer of the fibrous substance comprising the polymer material to produce carbon fibers, and (2) a method for producing carbon fibers, which comprising the steps of jetting a carbon black-dispersed and polymer material-containing solution by an electrospinning method to form a deposit layer of a fibrous substance comprising the carbon black-dispersed polymer material and irradiating microwaves to the deposit layer of the fibrous substance to produce carbon fibers.
