HYDROGEN STORAGE COMPOSITE FORMED ARTICLE AND METHOD FOR PREPARING THE SAME

The present invention relates to a hydrogen absorbing composite compact comprising silicone resin, and a process for making the compact, the compact being without particle size reduction or decay even when absorptions and desorptions of hydrogen are repeated for a long period of time and excelling in heat resistance, moldability and processibility. More particularly, the present invention provides a hydrogen absorbing composite compact which comprises hydrogen absorbing alloy and preferably 0.5 to 50% by weight silicone resin. Furthermore, the present invention provides a process for making the hydrogen absorbing composite compact comprising a step wherein a hydrogen absorbing alloy powder is molded by compression, a step for impregnation in a silicone resin solution or dispersion liquid and a sep for curing, and a process for making the hydrogen absorbing composite compact comprising a step for mixing a hydrogen absorbing alloy with any one selected from silicone resin itself, a silicone resin solution and a silicone resin dispersion liquid, a step for molding and a step for curing.
