    摘要： In a hydrogen concentration measurement device that employs a proton conducting electrolyte membrane, more stable measurement of hydrogen concentration that is less susceptible to temperature and humidity state of measurement target gas becomes possible.
    A hydrogen concentration measurement device for measuring concentration of hydrogen contained in measurement target gas, including a hydrogen permeation module having an entrance electrode and an exit electrode provided with a proton conducting electrolyte membrane sandwiched therebetween, the hydrogen permeation module selectively permeating hydrogen contained in the measurement target gas to the exit electrode by having the measurement target gas introduced into the entrance electrode and also by having current flowing between the entrance electrode and the exit electrode, and concentration of hydrogen contained in the measurement target gas is calculated based on, with the target gas introduced into the entrance electrode and with the current flowing between the entrance electrode and the exit electrode, a reaching time period ranging from a predetermined start time at which the current was initially applied to a time at which time rate of change of applied voltage between the entrance electrode and the exit electrode reaches a predetermined time rate of change.
