Customer:
General Motors

Request:
New proton conducting membranes for hydrogen-fuel cell powered vehicles with an improved performance profile, especially in climatically demanding regions, are to be developed.

Solution: New polymers
Development of new hydrocarbon membranes that work without fluorine-containing components and show a significantly improved conductivity with little swelling, and also significantly better mechanics.

Result:
Polymaterials membrane with clearly superior performance values compared to membranes containing fluorine.

  • At the time, the only fluorine-free fuel cell membrane performing at the level of the reference membranes
  • More ecological solution
  • Patented by GM (US7993792B2 & DE102007034752 (B4))Development of new hydrocarbon membranes that work without fluorine-containing components and show a significantly improved conductivity with little swelling, and also significantly better mechanics

Customer:
European specialty chemicals company

Request:
Biopolymer (polylactide – PLA) with significantly improved mechanical properties (toughness) and hydrolysis resistance with highly cost efficient production process at the same time.

Solution: New polymers and new compounds
In an integrated project between our synthesis lab and pilot plant, a reactive extrusion process of lactide and co-monomers in a planetary roller extruder was established. In addition, comprehensive database of blends and compounds to cover a wide range of properties was set up.

Result:

  • Largest PLA compound database
  • PLA grade for injection molding with the fastest crystallization time
  • Tough PLA types using small amounts of co-monomers

General Motors

Request:
Fluorine free proton conducting membranes with performance and durability comparable to PFSA-membranes.

Solution:
Polymer electrolyte membranes from polyperfluoro sulfonic acids (PFSA) such as Nafion, Flemion, Aciplex etc. are the typical choice for proton conducting membranes in PEM fuelc cells and electrolysers.

Fluorine free polymers based on polyarylene ethers like the SPATS-Triblock copolymers developed by Polymaterials can indeed achieve comparable performance and durability for the application in PEM fuel cells.

Result:
Comparable performance like PFSA-membranes, even under reduced humidity, partly higher durability then Nafion.
