Abstract

An apparatus includes a proton-conducting electrolyte membrane, an anode, a cathode, a first flow path which is disposed on the anode and through which an anode fluid containing hydrogen as a constituent element flows, a second flow path which is disposed on the cathode and through which hydrogen flows, a voltage applicator, a detector which detects a hydrogen cross leak amount passing through the membrane, where the detector detects the hydrogen cross leak amount from, a natural potential of one electrode of the cathode and the anode after forming a state where hydrogen is present at the one electrode and hydrogen is not present at the other electrode of the cathode and the anode, or a current flowing between the anode and the cathode when the voltage is applied from the voltage applicator in a state where the first flow path and the second flow path are both sealed off.
