Hydrogen sensor, hydrogen detecting method, and non-transitory computer-readable storage medium

Abstract

According to one embodiment, a hydrogen sensor is disclosed. The hydrogen sensor includes a capacitor, a gas detector, a heater, and a determiner. The capacitor includes a deformable member that deforms by absorbing or adsorbing hydrogen and varies a capacitance value corresponding to a deformation of the deformable member. The gas detector detects gas based on a capacitance value of the capacitor. The heater heats the deformable member. The determiner determines whether gas detected by the gas detector contains a substance other than hydrogen or not, wherein the gas detector detects the gas during a heating period during which the heater heats the deformable member.

What is claimed is: 
     
         1 . A hydrogen sensor comprising:
 a capacitor including a deformable member configured to deform by absorbing or adsorbing hydrogen and configured to vary a capacitance value corresponding to a deformation of the deformable member;   a gas detector configured to detect gas based on a capacitance value of the capacitor;   a heater configured to heat the deformable member; and   a determiner configured to determine whether gas detected by the gas detector contains a substance other than hydrogen or not, wherein the gas detector detects the gas during a heating period during which the heater heats the deformable member.
