METHOD OF ACTIVATING HYDROGEN ABSORBING BODY, METHOD OF HOUSING HYDROGEN ABSORBING BODY IN HYDROGEN STORAGE APPARATUS AND HYDROGEN STORAGE APPARATUS

摘要

PPROBLEM TO BE SOLVED: To provide a method of simply activating a hydrogen absorbing alloy before a hydrogen absorbing body containing the hydrogen absorbing alloy is housed in a hydrogen storage apparatus. PSOLUTION: The method of activating the hydrogen absorbing body is constituted so as to include a hydrogen absorbing body preparing process for preparing the hydrogen absorbing body containing the hydrogen absorbing alloy and an inert gas treating process for housing the hydrogen absorbing body in a treating vessel and holding at 100C under an inert gas atmosphere. The hydrogen absorbing alloy is easily activated by carrying out the inert gas treatment even if an activation treatment at a high temperature under the pressurizing of hydrogen is not carried out. It is needless to carry out the conventional activation in the hydrogen storage apparatus by housing the hydrogen absorbing body treated with the insert gas in the hydrogen storage apparatus as the hydrogen absorbing body is under the inert gas atmosphere. Then, a heating apparatus is unnecessary in the hydrogen storage apparatus to realize a small sized lightweight hydrogen storage apparatus. PCOPYRIGHT: (C)2004,JPO
