“…However, the PBI membrane has been identified as the best option from the point of view of a combination of performance and minimized SO2 cross-over, with a 27% increase in current density. This contrasts with later work also using cross-linked PBI blended membranes for this process, but without revealing any advantages in comparison with Nafion membranes [121,122].…”

AbstractThis review is devoted to membrane electrolysis, in particular utilizing ion-selective membranes, as an important part of both existing and emerging industrial electrochemical processes. It aims to provide fundamental information on the history and development, current status and future perspectives of membrane electrolysis. It aims to provide fundamental information on the history and development, current status and future perspectives of membrane electrolysis. An overview of the history of electromembrane processes is given with the focus on brine electrolysis since it is the predominant electrochemical industrial technology utilizing ion-selective membranes. This is followed by a summary of the wide range of hydrogen-based energy conversion processes with different degrees of maturity, i.e. water electrolysis and fuel cells, which promise to become the next generation of major electromembrane processes. The overview of the state-of-the-art is rounded off by a number of smaller-scale processes utilizing ionically conducting solid electrolytes and ion-selective membranes that are already commercially available. The article concludes by considering potential future developments in this exciting field of electrochemistry.

“…All membrane samples were tested using an acid treatment step adopted from literature [8] which included membrane drying, acid treatment and again drying while the thickness and weight changes of each sample was recorded for each step. The membranes were placed in 80 wt % H 2 SO 4 at 80 C for 120 h before drying the treated membranes in air at 80 C for 12 h.…”
