Poly(Alkyl-Terphenyl Piperidinium) Ionomers and Membranes with an Outstanding Alkaline-Membrane Fuel-Cell Performance of 2.58 W cm(-2)
Aryl-ether-free anion-exchange ionomers (AEIs) and membranes (AEMs) have become an important benchmark to address the insufficient durability and power-density issues associated with AEM fuel cells (AEMFCs). Here, we present aliphatic chain-containing poly(diphenyl-terphenyl piperidinium) (PDTP) copolymers to reduce the phenyl content and adsorption of AEIs and to increase the mechanical properties of AEMs. Specifically, PDTP AEMs possess excellent mechanical properties (storage modulus>1800 MPa, tensile strength>70 MPa), H-2 fuel-barrier properties (<10 Barrer), good ion conductivity, and ex-situ stability. Meanwhile, PDTP AEIs with low phenyl content and high-water permeability display excellent peak power densities (PPDs). The present AEMFCs reach outstanding PPDs of 2.58 W cm(-2) (>7.6 A cm(-2) current density) and 1.38 W cm(-2) at 80 degrees C in H-2/O-2 and H-2/air, respectively, along with a specific power (PPD/catalyst loading) over 8 W mg(-1), which is the highest record for Pt-based AEMFCs so far.
But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 5111-65-9, you can contact me at any time and look forward to more communication. COA of Formula: C11H9BrO.
