    Abstract: PURPOSE: A porous anode active material is provided to suppress stress and to ensure a high capacity compared with a conventional carbon-based anode active material by introducing some silica to a high-capacity active material. CONSTITUTION: A porous anode active material comprises 85-99 parts by weight of Group 14 oxides(10) and 1-15 parts by weight of silica(11) in a deactivation phase which does not react with lithium. A method for preparing the porous anode active material comprises the steps of: impregnating a Group 14 element salt-containing aqueous solution, including Group 14 elements salt and solvent in mesoporous silica(OMS); forming Group OMS-14 element oxide complex by heating the resultant; and etching the resultant with acid or a base solution.

    Abstract: Hierarchical mesoporous carbon and a method for manufacturing the same, and a fuel cell are provided to supply fuel, move by-products easily and to offer an electrode using a support catalyst including the hierachical mesoporous carbon. Hierarchical mesoporous carbon includes mesopores of which average diameter is 2nm excess or 50nm or less, 20nm excess or 50nm or less, and 2nm excess or 10nm or less. The mesopores of which average diameter is 2nm excess or 10nm or less has total volume more than 80% of total porosity volume. The mesopores of which average diameter is 20nm excess or 50nm or less has volume more than 3% of the total porosity volume. The mesopores of which average diameter is 10nm excess 20nm or less has the volume of 6% ~ 10% of the total porosity volume.
