HYDROGEN OCCLUDING AGENT, HYDROGEN OCCLUDING METHOD AND HYDROGEN OCCLUDING CARBON

摘要

PROBLEM TO BE SOLVED: To provide a hydrogen occluding agent comprising carbon fibers having new structural characteristics wherein a carbon fiber interlaminar reaction product is formed, a hydrogen occluding method using the same and hydrogen occluding carbon obtained by this method. SOLUTION: Hydrogen is brought into contact with the carbon fiber interlaminar reaction product, which contains a carbon structure wherein a diffraction peak position (2) due to wide angle X-ray diffraction analysis appears at 9-14 deg. and obtained by electrochemically treating carbon fibers in an acidic solution, is brought into contact with hydrogen to be occluded by the carbon fiber interlaminar reaction product.
