Poly(carbazole)-based anion-conducting materials with high performance and durability for energy conversion devices

Abstract

Anion conducting polymers (ACPs) are essential materials for alkaline electrochemical energy technology such as anion-exchange membrane fuel cells (AEMFC) and water electrolysers (AEMWE). The aforementioned polymers are promising alternatives for...

Recent Advancement on Anion Exchange Membranes for Fuel Cell and Water Electrolysis

“…Next, PCAEM and FAA‐3‐50 membranes were evaluated for AEMWEs using IrO 2 and Pt/C as anode and cathode catalysts, respectively. The PCAEM delivered the AEMWE performance of 3.495 A cm −2 at 1.9 V at 70 °C in 1 M KOH (Figure 7a) [75] . The performance (1.470 A cm −2 ) was much lower when FAA‐3‐50 membrane was used (Figure 7a).…”

“…Cha et al synthesized poly(carbazole)-based anion exchange membranes (PCAEM) for AEMFCs and AEMWEs. [75] Commercially available FAA-3-50 membrane was used to compare with PCAEM. For PCAEM, the AEMFCs performance was as high as 1.61 W cm À 2 at 60°C using PtRu/C and Pt/C as anode and cathode catalysts, respectively (Figure 6a).…”
