This study analyzed the room-temperature hydrogen uptake capacity of porous carbons prepared by carbonizing ion exchange resin. The ion exchange resin precursors were carbonized at 900℃, 1 hr, and N2 flow conditions. After carbonization, the porous carbons were synthesized by chemical activation. The effect on the quantity of activation reagents was investigated by the experience of carbon precursor/chemical reagent mass ratio. The structural information of the activated carbons was measured by X-ray diffraction (XRD) patterns. The N2 adsorption-desorption isotherms were measured at 77 K and calculated by Brunauer-Emmett-Teller (BET) equation. Hydrogen storage capacity was evaluated with a Model BEL-HP instrument (BEL Co., Ltd., Japan) at 298 K and 6 MPa.
