Problems solved by technology

[0003] General hydrogen storage alloy powder is in a dry and flowable state, but when a gel-like resin and carbon fiber with a viscosity of 500mPa·s to 10000mPa·s and a consistency are added and mixed to the hydrogen storage alloy powder in an appropriate amount , because the hydrogen storage alloy contained in the resin composite material is a wet sand-like hydrogen storage alloy, it becomes difficult to fill the alloy into a cylindrical hydrogen storage alloy container having a small mouth (opening) as a pressure vessel

Embodiment

[0108] Examples of the present invention will be described below while comparing with comparative examples.

[0109]

[0110] An aluminum cylinder having an inner volume of 800 mL and an opening inner diameter of 14 mm was prepared. In addition, prepare AB with an average particle size of about 700 μm 5 Alloy-like, 3.5% by mass of a gel-like silicone resin having a viscosity of 1000 mPa·s and a 1 / 4 consistency at 25°C of 85, and 2% by mass of a diameter of 10 μm, a length of 6 mm, and an aspect ratio of 600 needle-shaped carbon fibers, and they are mixed and stirred to obtain a resin composite material.

[0111] use figure 1 The device shown in , with the target filling rate set at 52%, filled the resin composite material into the container while applying vibration at a vibration frequency of 50 Hz, a displacement of 1.6 mm, and a vibration time of 5 minutes middle.

Abstract

The purpose of the present invention is to make it possible, when loading a hydrogen-absorbing alloy, to load the hydrogen-absorbing alloy easily and uniformly. The present invention pertains to a method for loading a hydrogen-absorbing alloy which has been made into a resin composite by mixing a pulverulent or particulate hydrogen-absorbing alloy, a resin, and carbon fiber, in which, when the hydrogen-absorbing alloy is loaded in a container, the container is caused to vibrate at a predetermined frequency to adjust the percentage of the container loaded with the hydrogen-absorbing alloy.

Description

technical field [0001] The present invention relates to a method for filling a container with a hydrogen storage alloy that has been made into a resin composite by mixing particles or powder of the hydrogen storage alloy with resin and carbon fibers. Background technique [0002] The hydrogen storage alloy is accommodated in the hydrogen storage alloy container and absorbs and releases hydrogen gas. However, because the hydrogen storage alloy itself expands and contracts by a maximum of 30% with the absorption and release of hydrogen gas, the stress generated at this time will strain the hydrogen storage alloy container, causing the container to deform, and in extreme cases, the container Cracks may form. As a method for relieving stress caused by alloy expansion and suppressing container strain, there is a method of containing a hydrogen storage alloy material that has been made into a resin composite material by mixing resin and carbon fiber with a hydrogen storage alloy ...
