Preparing a sulfonated poly(1,3,4-oxadiazole) polymer (I), comprises: producing a solution by mixing hydrazine sulfate salt with a non-sulfonated dicarboxylic acids or their derivatives in polyphosphoric acid; heating the solution under an inert gas atmosphere; and precipitating sulfonated poly(1,3,4-oxadiazole) polymer in a basic solution. Independent claims are included for: (1) a sulfonated poly(1,3,4-oxadiazole) polymer produced by the method; (2) a membrane for fuel cells made of (I) comprising bonding sulfonic acid groups with the main chain of the polymer, where the membrane has a feed side and a permeate side; (3) a fuel cell with the membrane; and (4) a method for the production of a fuel cell, comprising: producing the membrane having a feed side and a permeate side; and disposing the membrane between two porous catalyst electrodes made of platinum or a platinum alloy, where the feed side of the membrane contacts an anode and the permeate side of the membrane contacts a cathode. |
