US 8,011,223 B2 · Remaining hydrogen sensor

Abstract

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.

Dependent claims

A hydrogen sensor, the sensor comprising:

a sensor main body configured to contain a sensor hydrogen storage alloy,
wherein the sensor main body comprises a deformable portion, the deformable portion deforms more in response to a hydrogen absorption/release of the sensor hydrogen storage alloy than other portions of the sensor main body, and a strain gauge for measuring a strain is provided on the deformable portion of the sensor main body,
wherein the sensor main body has a cylinder shape and has a notched portion in a cylinder wall to extend over a full length in an axis direction, and the deformable portion is disposed in a cylinder wall opposing the notched portion.
