By the method of low temperature 1H NMR spectroscopy in quasiisobaric conditions (P =1.1•105 Pa) hydrogen adsorption was studied on activated carbons (AU) obtained by carbonization of porous phenol-formaldehyde resin with subsequent activation of CO2 with a 86% (AU-86) and 47% (AU-47)scorch degree. It was shown that hydrogen adsorption in the pores of AU-86, with a specific surface area of 3463 cm2/g became five-fold higher for increased concentrations of reabsorbed water. In the case of presence of 40 mg/g H2O in a sample, hydrogen adsorption reaches 1.4 mg/g at T = 200 K. It was established that adsorbed hydrogen is localized in gap-like micropores, in the porous areas of which the screening effect of the surface is equal to zero. The results are explained in the terms of the three minima existence at the intersection of the potential adsorption energy curve of gap-like pores, two of which are located near the pore walls (where the surface screening effect is high), and the third one is in the centre of the pore (with the screening effect close to zero). All adsorbates (water, saturated hydrocarbons) except hydrogen are localized mainly at the walls of the pores. The water can move to the middle area of the pores with temperature decreasing, which reduces the screening effect of the surface. Adsorbed hydrogen is localized only in the middle area of pores.
A comparative analysis of electro-physical properties of several fuel cells series was held and it was shown that there is a possibility of non-platinum effective hydrogen solid elements creation with further optimization of nanocatalysts technological synthesis conditions on the surface of carbon electrodes.
