    摘要： PURPOSE: A crosslinked polymer is provided to contain the large amount of phosphoric acid by cross-linking, thereby having superior hydrogen ion conductivity, and improving thermal stability, chemical stability and physical strength. CONSTITUTION: A crosslinked polymer comprises a structure in the chemical formula 1. In the chemical formula 1, X is NR, and O or S, m is the integer of 3-6, and n is the integer of 1-1000. The manufacturing method of the phosphoric acid - doped electrolyte membrane comprising the crosslinked polymer comprises: a step of manufacturing a copolymer by polymerizing 1,3,5-benzene tricarboxylic acid and a compound in the chemical formula 8 in nitrogen atmosphere; a step of adding phosphoric acid; a step of reacting the copolymer with a cross-linking agent; and a step of impregnating the crosslinked polymer electrolyte membrane into phosphoric acid aqueous solution.
