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) cop...

| description | 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), H2 fuel‐barrier properties (7.6 A cm−2 current density) and 1.38 W cm−2 at 80 °C in H2/O2 and H2/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.
Poly(alkyl‐terphenyl piperidinium) membranes and ionomers display outstanding hydrogen‐barrier properties and mechanical properties as well as excellent hydroxide‐ion conductivity that results in an excellent power density of 2.58 W cm−2 and 1.38 W cm−2 at 80 °C in H2/O2 and H2/air, respectively, along with a new, outstanding specific power in alkaline‐exchange‐membrane fuel cells. |
