Abstract
A hydrogen quantity sensor can directly measure hydrogen contained in a hydrogen storage device with simple and easy means. The hydrogen quantity sensor comprises a detecting electrode comprised of a hydrogen storage alloy disposed inside a hydrogen storage vessel, a standard electrode disposed to confront the detecting electrode; and an electrolyte member disposed between the detecting electrode and the standard electrode. The detecting electrode, the standard electrode and the electrolyte member constitute a sensor portion to measure hydrogen concentration within the hydrogen storage alloy as an electromotive force value.
Claims6
A hydrogen quantity sensor comprising:
- a first sensor portion which detects hydrogen concentration in a high concentration range;
- and
- a second sensor portion which detects hydrogen concentration in a low concentration range,
- wherein each of the first sensor portion and the second sensor portion comprises:
- (i) a detecting electrode comprised of a hydrogen storage alloy disposed inside a hydrogen storage vessel;
- (ii) a standard electrode disposed confronting the detecting electrode;
- and
- (iii) an electrolyte member disposed between the detecting electrode and the standard electrode,
- wherein each of the sensor portions measures an electromotive force value, and
- wherein the detecting electrode of the first sensor portion is comprised of a different hydrogen storage alloy than the detecting electrode of the second sensor portion.
