Abstract

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.

Description

technical field

[0001] The present invention relates to a hydrogen-absorbing composite molded body comprising a silicone resin and a method for producing the molded body, and, more particularly, to a hydrogen-absorbing composite molded body comprising a hydrogen-absorbing material and a silicone resin binder A composite molded body whose particle size does not decrease or change when hydrogen adsorption and desorption are repeated for a long time, and also relates to a production method of the composite molded body. Background technique

[0002] Hydrogen-absorbing alloys have been gradually used as hydrogen separation or purification materials, catalysts, sensors, etc., as well as hydrogen-absorbing materials for stationary storage tanks, hydrogen sources for fuel cells and hydrogen-fueled vehicles, and in the use of hydrogen adsorption and hydrogen absorption. Endothermic and exothermic properties upon desorption of energy conversion materials in heat storage systems, etc. ...
