    • The invention relates to a porous proton-conducting material which comprises an inorganic-organic network representing a metal-organic complex of a coordinating metal cation with an aromatic compound, which compound comprises a) a rigid core, preferably consisting of at least one of the following building blocks: benzene, naphthalene, anthracene, triphenylbenzene, tetraphenylmethane, adamantyl, or structurally related compounds in particular other condensed aromatic ring systems, b) a spacer region comprising at least one rigid unit selected from the group consisting of phenylene, polycyclic aromatic hydrocarbons, and acetylene, linked to the rigid core, and c) a peripheric region comprising at least 2 acidic substituents selected from the group consisting of phosphonic acid, hypophosphorous acid, sulfonic acid, carboxylic acid, arsenous acid and hypoarsenous acid, wherein the molar ratio of the metal cation to the acidic groups of the aromatic compound is below 1 and a fraction of uncoordinated free acidic groups is still present in the complex, and wherein the porous proton-conducting material further comprises a dopant, which is selected from the group of oxoacids and N-heterocycles, in the pores thereof. In an especially preferred embodiment, the aromatic compound of the inorganic-organic network is phosphonic acid functionnalized hexakis (phenyl) benzene (HPB), the coordinating metal cation is Al 3+ and the dopant is H 3 PO 3 . The invention further relates to a proton-exchange membrane and a fuel cell comprising said proton-conducting material.
