What is Polyelectrolite Membrane?

Nowadays, the production of new polymers material is evolved as the electrolyte polymer membrane is developed. Of the many types, the developed electrolyte polymer membrane, which was developed, is one of them membrane ion exchangers or polymer exchanger membrane (PEM), are based on perfluorous polymers or performat acid, for example, NAFION®. Nafion It is a membrane that is the main selection and easy to find is due to the nature of high ion conductivity, chemical stability and high mechanical (Martins et al., 2003). In addition to the expensive price, there are some things that the time of use (life), that is, degradation, restricted, corrosive temperature and operation. Nafion® In its application is a limited temperature that is, can not exceed 80 or C (Handayani et al., 2007). Some methods were used to overcome the problem of limiting the applications of fuel cells. Among them are new materials that can be used as a substitute Nafion®, which has high thermal stability and is relatively cheap. Currently it starts with the development of polymers to overcome. Problems using Nafion®. Requirements that must be filled with polymers, since the membrane of the fuel cell is loaded, therefore the modification must be made. A method which can be prepared for charged polymers. It is sulfonation. Other modifications that can be made in the polymers. It's the connection. The purpose of the polymer compound is to produce. New material with better characters, including thermal, mechanics and more conductivity (Jamal et al., 2007).
