In the hydrogen energy system, polymer material will be widely utilized as functional material. Rubbers are utilized as sealing material at the joint between pipings. Polymer electrolyte membranes are utilized as ionic conductor and as the partition between electrode. A farther performance for the polymer materials is required because the present polymer material has a permeability to hydrogen, which can not be negligible, resulting in the lower durability of it. We are fabricating an equipment, which can measure the hydrogen solubility and diffusivity in polymer material; these physical data obtained will be available for designing the material itself and hydrogen system. This equipment captures the hydrogen molecular properties with receiving the signal from a small NMR-sensor inserted in the polymer sample surrounded in a pressurized hydrogen-gas atmosphere. Here, the test measurement of the NMR signal for H2O/D2O mixture solution is shown.
