From: Upscaled production of an ultramicroporous anion-exchange membrane enables long-term operation in electrochemical energy devices

Fig. 5

a Schematic diagram of AEMWEs assembled with the MTCP-50 AEM (25 ± 2 µm) and the conduction of OH− ions across the membrane matrix. b I–V curves of versus temperature with 1 M KOH feed. c EIS spectra of AEMWEs versus temperature under 1 M KOH feed. d Summary of current densities at 1.8 V of current AEMWEs (MTCP-50 fed with 1 M KOH, pink; MTCP-50 fed with pure water, blue; proton exchange membrane, purple). e I–V curves of versus temperature with pure water feed. f EIS spectra of AEMWEs versus temperature under pure water feed. g Long-term durability of AEMWEs under 0.5 A cm−2 at 60 °C for 2500 h and 1.0 A cm−2 at 80 °C for 500 h. h Comparison the durability of 1 M KOH-fed alkaline electrolyzers with current state-of-the-art AEMWEs (Refer to Supplementary Table 6).
