High-performance anion exchange membrane water electrolyzers with a current density of 7.68 A cm⁻² and a durability of 1000 hours

Abstract

Poly(fluorenyl-co-aryl piperidinium)-based AEMWEs reach outstanding current density values of 7.68 A cm−2 at 2.0 V with a cell durability of 1000 h.

Construction of Integrated Electrodes with Transport Highways for Pure‐Water‐Fed Anion Exchange Membrane Water Electrolysis

“…In contrast, ionomer‐free self‐supported electrodes are unable to use in pure‐water‐fed AEMWE due to the absence of hydroxide ion transport pathways in the CL. [ 19,20 ]…”

Di-piperidinium-crosslinked poly(fluorenyl-co-terphenyl piperidinium)s for high-performance alkaline exchange membrane fuel cells

“…5d and S13† indicate a 5% to 10% decrease in the ratio of hydrophilic phase area after alkaline treatment in 1 M NaOH at 80 °C for 1200 h. These durability results suggest the present di-piperidinium crosslinked AEMs as a good candidate for durable alkaline energy devices. 37…”

Robust and durable poly(aryl-co-aryl piperidinium) reinforced membranes for alkaline membrane fuel cells

“…Gas tightness is a basic and crucial requirement of AEMs applied in alkaline energy devices such as AEMFCs and anion exchange membrane water electrolysis devices. 49 AEMs with qualied gas tightness, especially for hydrogen and oxygen, can secure the long-term operation of AEMFCs. The hydrogen permeabilities of pristine membranes and RCMs at different RHs were evaluated at 60 C with 2.2 bar of unilateral back pressure, as shown in Fig.…”
