Carbon Fiber for a Fuel Cell with Catalytic Metal Support    

A carbon fiber with catalytic metal support is a carbon fiber in which numerous hexagonal carbon layers in the shape of a cup that have no bottom are stacked.

Overview

This provides a carbon fiber having catalytic metal support, capable of remarkably increasing a catalytic effect due to the reduced size of the support and the capability of supporting a large number of catalytic metal particles. Conventionally used carbon black has a large diameter of several hundreds of nanometers and deposition of catalytic metal is non-uniform, therefore support efficiency of catalytic metal is poor. This gives rise to a problem that a sufficient catalytic effect cannot be obtained. This new technology can solve such problems caused by the conventional carbon black.

Primary Application of the Technology

Fuel cell market

The Problem Solved by the Technology

Conventionally, carbon black on which catalytic metal is supported is known. Carbon black has a large diameter of several hundreds of nanometers and deposition of catalytic metal is non-uniform, so support efficiency of catalytic metal is poor. This gives rise to a problem that a sufficient catalytic effect cannot be obtained. This new technology can solve such problems caused by conventional carbon black.

How the Technology Solves the Problem

This technology provides a carbon fiber with catalytic metal support, consisting of a coaxial stacking morphology.

Patent Summary

U.S. Patent Classes & Classifications Covered in this listing:

Class 423: Chemistry Of Inorganic Compounds

This class provides for what is generally termed the field of inorganic chemistry. It includes inorganic compounds, nonmetallic elements and processes of producing the same involving a chemical reaction. The products are generally in a relatively pure state but may be a mixture with no other utility than as a source material for an inorganic compound or element. This includes metal compound products useful in metallurgical processes of obtaining free metals.

Subclass 447.1: Fiber, fabric, or textile
Subclass 447.2: Product
Subclass 447.3: From gaseous reactants

Class 428: Stock Material Or Miscellaneous Articles

This is the residual class for: 1. Stock material in the form of a structurally defined web, sheet, rod, strand, fiber, filament, cell, flake, particle not provided elsewhere. 2. Stock material in the form of a web, sheet, mass or layer which consists of or contains a structurally defined constituent or element. 3. A nonstructural laminate defined merely in terms of the composition of one or more layers. 4. An article of manufacture or an intermediate-article not provided for elsewhere. 5. A process for applying an impregnating material to a naturally solid product such as a wood beam, a sheet of leather or a stone, or for applying a coating to a base, and which process includes no significant method step.

Subclass 367: Including free carbon or carbide or therewith (not as steel)
