Conventional sources of energy are limited on the earth. Processing, isolation and purification of final product from these natural resources for energy production are very costly and harmful to the environment. Therefore, materials made with the available synthetic tools in the laboratory are desired as an alternative to oil and gas to meet energy demand and reduce the negative impact on environment. In this direction, organic light emitting diodes (OLED), field effect transistors (FET) and solar cells are currently being constructed with their organic counterparts. One step further, nowadays fuel cell batteries are being used in automotives, space crafts and submarines due to their wide range of applications and greater market values. A typical fuel cell (FC) utilizes methanol or hydrogen as a fuel and an ionic membrane between its electrodes for producing the electricity. Here in, we report a different class of battery materials with higher performance. Synthetic materials based on ionic organic acids and bases were designed and synthesized. These functional ionic entities were obtained by employing the easiest synthetic routes and from their cheaper commercially available parental compounds. Conductivity experiments done by the Impedance Spectroscopy have shown a higher performance up to 10-2 S/cm which is just one magnitude lower as compared to that of commercialized ionic materials used in fuel cell batteries. Thermal stability up to 180 C as investigated by thermal gravimetric analysis enables these ionic complexes to be integrated as a membrane insulator within proton exchange fuel cells in which methanol or hydrogen is used as a fuel and thereby excluding the usage of combustion fuel that produces harmful greenhouse gases.
