| titleOfInvention | Proton exchange membrane for use in proton exchange membrane fuel cells |
| abstract | The use of a proton exchange membrane M in proton exchange membrane fuel cells, in particular in a polymer electrolyte membrane fuel cell or a direct methanol fuel cell, in which the exchange membrane M of protons comprises at least one partially sulfonated polybenzimidazole polymer ps-PBI comprising, in polymerized form, at least 90 mol% of monomeric U units of formula (I) and / or (II), based on the amount Total monomer units in the partially sulphonated polybenzimidazole polymer ps-PBI. ** Formula ** in which L, L1 and L2 are independently selected for each of the monomeric U units and are selected, independently from each other, from the group consisting of hydrogen and -A-SO3H, wherein A is selected from the group consisting of divalent C1-C10 alkanediyl; divalent C1-C10 fluoroalkanediyl; and C7-C15-divalent alkyl aryl; wherein A is preferably selected from the group consisting of divalent linear C1-C10 alkanediyl; linear C1-C10 fluoroalkane divalent; and C7-C12-divalent alkyl aryl; Y is selected from the group consisting of O and S, or Y is a carbon-carbon single bond; Z is selected from the group consisting of divalent C1-C10 alkanediyl, divalent C2-C10 alkenodiyl; divalent C6-C15 aryl; divalent C5-C15 heteroaryl; divalent C5-C15 heterocyclyl; divalent C6-C19-sulfone aryl; and C6-C19-divalent ether aryl, wherein Z is preferably selected from the group consisting of divalent C4-C8 alkanediyl, divalent C2-C4 alkenodiyl; divalent C6-C12 aryl; divalent C5-C12 heteroaryl; divalent C5-C12 heterocyclyl; divalent C6-C12-sulfone aryl; and C6-C12-divalent ether aryl; and wherein the total amount of monomeric U units in the partially sulfonated polybenzimidazole polymer ps-PBI is from about 100 to about 10,000; wherein from about 40 to about 85 mol% of L, L1 and L2, based on the total amount of L, L1 and L2 is a remainder -A-SO3H; and characterized by the fact that the membrane M is essentially free of water and exhibits a proton conductivity at a temperature of 100 ° C or more, preferably in the range of 100 to 250 ° C, of at least 1 x 10-5 S / cm , as measured by the impedance method, in which the proton exchange membrane fuel cell is operated at a temperature of 100 ° C or more, preferably in the range of 100 to 250 ° C, under conditions where the Proton exchange membrane M is essentially free of water, and in which membrane M has a water content of 10% by weight or less, based on the total weight of membrane M. |
