Green fabrication of pore-filling anion exchange membranes using R2R processing

Autor: Haejun Jeong, Hanki Kim, Jiyeon Choi, Sung Yong Byeon, Youngwoo Choi, Heesung Yoon, Namjo Jeong, Yong Ho Kim, SeungCheol Yang

Publikováno v: Journal of Membrane Science. 584:181-190

Pore-filling ion exchange membranes are fabricated by complicated and energy-inefficient processes, use of large amounts of polar organic solvents, and optionally post-modification using acid or base. For green fabrication of pore-filling anion excha

Electrode system for large-scale reverse electrodialysis: water electrolysis, bubble resistance, and inorganic scaling

Autor: Joo-Youn Nam, Haejun Jeong, Hanki Kim, Chan-Soo Kim, Namjo Jeong, Sung-Yong Byeon, SeungCheol Yang, Ji-Hyung Han, Kyo-Sik Hwang, Jiyeon Choi

Publikováno v: Journal of Applied Electrochemistry. 49:517-528

It is generally accepted that the effect of electrode resistance is not predominant in determining the performance of reverse electrodialysis (RED), because the contribution of electrode resistance to total internal resistance decreases as the number
