Fuel Cell Membranes

One of the most important pillars of fuel cells is design of proper membrane for exchange of substances between two electrodes. Various aspects of membranes were investigated, such as: structural and thermal properties, proton conductivity, pore characteristics, hydrogen permeability, elastic modulus, mechanical and thermal stability and performance in fuel cell tests. Various membranes have been used in fuel cells, for example: proton exchange membrane, glass composite membrane, polymer electrolyte membrane, nano composite membranes, hydrocarbon membrane, clay modified with silane, proton conducting membrane used in fuel cells. Each membrane is designed for specific propose, and has advantages and disadvantages. In this paper we would like to introduce structure, advantages and disadvantages of fuel cell membranes.
