Abstract
|
The state- of- the- art of membrane technology is characterized
by a number of mature applications like PEM fuel cells,
electrolyzers, electrodialysis and etc. Amongst them, brine
electrolysis technology is considered as an intensive energy
consumption (0.6% of global power) [1,8]. This is further
underlined that membrane electrolysis is favored as an efficient
energy consumption technology in comparison with mercury
and diaphragm ones [7]. It is apparent that, cation exchange
membranes (CEMs) is regarded as a prominent component in
such systems which are currently composed of established
materials including polymeric or inorganic material and
feasibly can be scalable manufacturing procedures like
interfacial polymerization, casting and coating. Furthermore,
some efficient polymers for tremendous potential in various
sub-disciplines of electrochemistry and polymer engineering.
The present overview explicitly provides the specifications of
brine electrolysis membranes that conduct sodium cations with
respect to prevention back migration of hydroxide anions,
namely chlor- alkali cation exchange membrane.
