By studying the properties of materials under proton irradiation, it was proven that under the influence of intermolecular factors, hydrogen is formed in molecular form in the defects. It is interesting to track its removal through the porous structures and its capture, so that it can be used as fuel in the conditions of long space flights. In the first experiment, theoretical models were examined in which the described effect is present. It is observed that the two parameters characterizing the quality of positron annihilation (S and W) have characteristic saturation extrema. This model experiment was confirmed in real measurements carried out on EG 5 and the positron beam to the positron spectroscopy sector. The next step forward is to determine the optimal materials for extracting molecular hydrogen, as well as to envision methods for extracting molecular hydrogen in space conditions.
