NOVELTY - A product (P1) comprising an organic superacid comprising a first acid group comprising a hydrogen bond, a second group comprising an electronegative atom, and an intramolecular hydrogen bond between the first acid group and the electronegative atom of the second group, is new.    USE - As proton conductive polymer useful in fuel cell (claimed).    ADVANTAGE - The fuel cell performance is enhanced by providing an organic based proton exchange membrane that exhibits improved proton conductivity at a low relative humidity. Allowing fuel cells to operate at a low relative humidity reduce the problems associated with cathode flooding, water management and freeze start up, and possibly lower the cost of operating a fuel cell.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following:    (1) polymerization (P2) of organic superdiacid monomer involving providing a polymerizable organic superdiacid monomer of formula (III); and polymerizing the polymerizable organic superdiacid monomer by way of a polycondensation reaction; and    (2) forming organic superacid involving: providing an organic superacid precursor molecule that comprises a first aromatic ring structure, a second aromatic ring structure, and an intermediate structure that comprises an -S- atom that links a ring carbon from the first aromatic ring structure to a ring carbon from the second aromatic ring structure; oxidizing the -S- atom of the intermediate structure to form a sulfonyl group; modifying the organic superacid precursor molecule to include at least one alcohol group located at any position on the first aromatic ring structure or the second aromatic ring structure that is meta- or para- to the sulfonyl bond; and forming an organic superacid by adding at least one acid group to at least one of the first aromatic ring structure or the second aromatic ring structure.    A2=sulfonic acid, carboxylic acid or phosphoric acid group;    Y2=O, S or direct carbon bond;    B2=alcohol, halide, NO2, low molar volume ether, low molar volume ester or low molar volume carbonate;    Z2=sulfonyl or carbonyl.    Provided that: In the formula (III), in the value of B2, at least two are alcohols.
