S. Venugopalanfluoride medium. Their general formula is M.(Al.)(Si..Al.)O.((OH).F.). (for a half-unit cell) with x being a value between 0 and 0.9 and y a value between 0 and 2. The substitution of fluorine atoms for hydroxyl groups increases the thermal stability. These layer silicates are the first stage toward

Polymer Electrolyte Membrane Fuel Cell,his assembly is normally called membrane electrode assembly (MEA) or EMA which is placed between the two flow field plates (bipolar plates) (Section 2.5) to form what is known as “stack”. The basic operation of the PEMFC is the same as that of an acid electrolyte cell as the mobile ions in the polymer are H. or proton.
