The application of fuel cell technology for the construction of a hydrogen permeation monitoring apparatus has been demonstrated. Using the testing material as an anode and the oxygen reduction reaction as an electron sink (cathode), it is possible to build such detectors, which have several advantages in comparison with the existing practice. These detectors make it possible to follow the internal corrosion, with a longer sensor life, and without external energy consumption. Preliminary field results are presented.
