  7. Abstract:
  8. Application of fuel cells as one of the new and clean energy generators at recent years is many interesting for governments. In many cases hydrogen gas is fuel of these cells. One of the problems at this field is issue of hydrogen storage with a safety and ecconemical way. Usually storage of hydrogen be done with several different ways : Composite tank, Liquid hydrogen, Metal hydride , Chemical hydride, carbon nanotube and etc. Use of polymers that have ability of adsorption is one of topics that is attended at these years , because of their low density and easy process ability and low explosion risk and economical aspect . So at this research we try to identify polymers that have ability of adsorption and examine their characteristics and properties and afterward one of them that have best condition for this mater be selected and finally FTIR test, BJH, Adsorption Isotherm, SEM and H2 Adsorption tests be done. Phenolic Network and Poly(divinyl_benzen ) be synthesized and FTIR and BJH tests are done for these materials. These experiments show that phenolic network´s pores size is 12 nm and poly(divinyl_benzen )´s pores size is 14.13 nm, so finally, phenolic network be selected for next examinations. Hydrogen adsorption test for phenolic network shows that this material at 1 bar can adsorb 0.0013 % wt . afterward for prediction of amount of adsorption at high pressure we use several isotherm model . Best model is Dubiinin-Rudushkevich that predict 4.65 % wt adsorption for 100 bar for the material. After ward we examine the effects of several parameters on porosity of polymer (polycarbonate/poly ethylene glycol). These parameters are nano clay adding, concentration of solution, adsorption temperature and surround PH .
