NOVELTY - Production of hydrogen involves exposing a chemical compound, e.g. a primary or secondary alcohol or amine or a heterocyclic compound, to catalytic dehydrogenation.    USE - For production of hydrogen useful in fuel cell (claimed).    ADVANTAGE - The catalyst lowers the energy required for storing and evolving hydrogen. The hydrogen can be stored and evolved at ambient temperature with minimal heat input. The method is thermodynamically more favored. The catalyst makes the hydrogen reaction reversible, allowing the organic compounds to function as reversible hydrogen carriers that are capable of carrying hydrogen form one region of the device to another.    DETAILED DESCRIPTION - Production (P1) of hydrogen involves exposing chemical compound to a catalyst for dehydrogenation, optionally with acid. The chemical compound (C1) is:    R1-CH(XH)-X'R2 (I), or cyclic compound of formula (II) - (VI).    X,X' = O, -N(H)- or -N(R3);    R1-R3 = H, alkyl, aryl, alkenyl, alkyl carboxylic acid, alkyl sulfonic acid, alkyl phosphoric acid, alkyl phosphonic acid, aryl carboxylic acid, aryl sulfonic acid, aryl phosphoric acid, aryl phosphonic acid, alkenyl carboxylic acid, alkenyl sulfonic acid, alkenyl phosphoric acid or alkenyl phosphonic acid;    R1+R3 = ring;    Q = -(C(R7R8))n, -(C(R7R8)-M-C(R7R8))-, -(C(R7)=C(R8))-, -(C(R7)=C(R8)-C(R9)=C(R1))-, -(C(R7)=N)- or -(C(R7)=N-C(R8)=N)-;    n = 1 - 10;    M = O, -NR9-, S or -C(=O)-;    Z = O, S or -N(R11)-;    R5,R11 = H, alkyl or aryl;    R7-R10 = R5, alkenyl, alkyl carboxylic acid, alkyl sulfonic acid, alkyl phosphoric acid, alkyl phosphonic acid, aryl carboxylic acid, aryl sulfonic acid, aryl phosphoric acid, aryl phosphonic acid, alkenyl carboxylic acid, alkenyl phosphoric acid or alkenyl phosphonic acid;    R6 = R7, -OR12, -N(H)(R12) or -N(R12R13);    R12,R13 = R5;    R7+R8,R8+R9 = ring;    Z' = O, S or -N(R'4)-;    Q' = O, -N(R'5)-, -(C(R'5R'6))n, -(C(R5)=C(R6))m or -(C(R5)=N)p-;    m,p = 1 - 2;    R'1,R'2,R'4-R'6 = alkyl or aryl;    R'3,R = H, alkyl or aryl;    Q1 = N or C(R');    R' = H, alkyl, aryl or higher fused ring.    Provided that X and X' are not both oxygen; at least one of R5 and R11 is H. INDEPENDENT CLAIMS are included for the following:    (1) system comprising (C1) and the catalyst;    (2) a fuel cell comprising anode and hydrogen-generating fuel source for the anode, the source comprising (C1) and the catalyst, optionally with electrocatalyst for facilitating the dehydrogenation of (C1);    (3) a method for storing hydrogen involving exposing a chemical compound to hydrogen or to a reducing agent in the presence of catalyst to hydrogenate the compound having an anion and cationic portion of formula (VII) or the chemical compound is R1-C(=X)-X'R2.
