An object of the present invention is to enable filling a hydrogen storage alloy uniformly and easily at the time of filling the hydrogen storage alloy. The invention relates to a method for filling a hydrogen storage alloy including, when the hydrogen storage alloy that has been made as a resin composite material by mixing hydrogen storage alloy particles or powder with a resin and carbon fiber is filled into a tank, vibrating the tank at a predetermined frequency to adjust a filling ratio of the hydrogen storage alloy in the tank.

Method for filling hydrogen storage alloy

A resin composition including a resin and a hydrogen storage alloy powder. When hydrogen gas is absorbed-released in a hydrogen storage vessel obtained by filling the resin composition in the vessel such that a ratio V2/V1 between a volume V2 of the hydrogen storage alloy powder and an inner volume V1 of the vessel becomes 40 to 80 vol %, a distortion &#x3b1; produced on a wall of the hydrogen storage vessel is 1,000&#xd7;10or less.

Composition comprising hydrogen storage alloy and resin

The invention comprises a hydrogen source, a detachable connecting port to which a hydrogen storage container is connected in order to store hydrogen supplied from the hydrogen source, a container cooling unit (an air blower) for cooling a hydrogen storage container connected to the connecting port, a container connection recognition unit (a limit switch, a controller) for recognizing connection of a hydrogen storage container to the connecting port, and a fill-up detection unit (a pressure transmitter, a hydrogen remaining sensor, a controller) for detecting that the hydrogen storage container connected to the connecting port is filled up with hydrogen. Consequently, it contributes to simple and safe hydrogen filling in the general public.

Hydrogen filling apparatus

In the hydrogen remaining sensor of the present invention, the hydrogen remaining sensor is arranged in a space in which the hydrogen is absorbed/released by the main hydrogen storage alloy, and is equipped with the vessel-like sensor main body in which the sensor hydrogen storage alloy is filled and through which the hydrogen is moved. Also, the easy-to-deform portion in which the strain is caused easily due to the hydrogen absorption/release of the sensor hydrogen storage alloy is provided to a part of the sensor main body, and the strain gauge for measuring the strain of the easy-to-deform portion is provided. As a result, according to the hydrogen remaining sensor of the present invention can contribute to sense precisely a remaining amount of hydrogen in the main hydrogen storage alloy.
