Abstract
Carbon fiber including graphitized fiber is processed electrochemically in an acidic solution for a time sufficient to run a layer reaction such that the reaction extends to the inside of the fiber and thereafter, as required, heat-treated accurately at 100° C. or more to expand layer spacing to form multifibrous carbon fiber, with which hydrogen is brought into contact, adsorbing hydrogen in the inside of the multifibrous carbon fiber.
