In this study, PVA-based profiled IEMs were prepared by mixing an ethylene-vinyl alcohol copolymer (EVOH) and PVA-based polyions, and then their basic properties and RED power generation performance were evaluated. By blending EVOH with a PVA-based block copolymer, we obtained flat-shaped cation and anion exchange membranes (F-CEM and F-AEM) that improve the mechanical strength of IEMs with a high transport number and low membrane resistance. The profiled CEMs (PF-CEMs) were prepared by hot-pressing F-CEMs. The stack using PF-CEMs/F-AEMs showed the maximum power output of 2.07 mW at 7.0 mA of current.
