  Tunable High Performance Cross-Linked Alkaline Anion Exchange Membranes for Fuel Cell Applications

  摘要：

  Fuel cells are energy conversion devices that show great potential in numerous applications ranging from automobiles to portable electronics. However, further development of fuel cell components is necessary for them to become commercially viable. One component critical to their performance is the polymer electrolyte membrane, which is an ion conductive medium separating the two electrodes. While proton conducting membranes are well established (e.g., Nafion), hydroxide conducting membranes (alkaline anion exchange membranes, AAEMs) have been relatively unexplored by comparison. Operating under alkaline conditions offers significant efficiency benefits, especially for the oxygen reduction reaction; therefore, effective AAEMs could significantly advance fuel cell technologies. Here we demonstrate the use of ring-opening metathesis polymerization to generate new cross-linked membrane materials exhibiting high hydroxide ion conductivity and good mechanical properties. Cross-linking allows for increased ion incorporation, which, in turn supports high conductivities. This facile synthetic approach enables the preparation of cross-linked materials with the potential to meet the demands of hydrogen-powered fuel cells as well as direct methanol fuel cells.

The resulting polymers were hydrogenated to yield the corresponding functional polyolefins that were structurally equivalent to copolymers of ethylene and either methyl methacrylate, t‐butyl acrylate, or acrylic acid after deprotection. The copolymers that incorporate methyl methacrylate into the

  The present invention is related to a linear functional polymer having repeating units A, B and D. Unit A represents —CH 2 —, unit B represents and unit D represents where R 1 represents a polar functional group. There are at least four A units separating each B unit, each D unit, and each B and D unit. The value y represents the total number of B units and is an integer greater than or equal to 1. The total number of D units is represented by h and is an integer greater than or equal to 0. And x represents the total number of A units and is an integer sufficient that the molar fraction of the B and D units in the linear functional polymer is represented by a value j defined by the equation: j = y + h x + y + h ≤ 0.032 . The present invention is also directed to a method for preparing such linear functional polymers by copolymerizing a first polar substituted monomer and a second non-polar unsubstituted monomer.
