Fuel cells have received considerable attention

Fuel E-64-c have received considerable attention as an alternative green technology of power source which can partially solve the energy crisis issues, global warming, environmental pollution and rapid depletion of the fossil fuel. Fuel cells are electrochemical devices those convert chemical energy directly to electrical energy using fuels such as hydrogen, methanol, natural gas. Fuel cells possess several advantages such as environmental friendliness, high efficiency and simplicity [1], [2] and [3]. Fuel cell, specifically polymer electrolyte membrane fuel cell (PEMFC) consists of a polymer membrane that separates anode and cathode and helps in conducting proton from the anode to the cathode. Nafion is considered to be the most widely used electrolyte membrane for PEMFC owing to their high proton conductivity, chemical stability and durability. However, the low proton conductivity at high temperature (>80 °C) and at low humidity conditions, along with its cost makes Nafion unsuitable for practical applications [3] and [4]. Hence, several approaches and new membrane materials have been devised to avoid the demerits of Nafion [4], [5], [6], [7] and [8].
