    Due to the increased demand of energy there would be a stern dispute in the near future as the efficient energy resources are soon to be ceased. To overcome such a challenging disagreement, we have to put our attention towards such novel energy conversion and efficient technology which can strengthen us against such problem. Fuel cells are promising devices for clean and efficient power generation. The electrolyte free fuel cell (EFFC) is an innovative, high-energy conversion and efficient generation of fuel cells which directly convert the chemical energy into electrical energy. In this research the mixed ionic and electronic conducting material will be equipped by desired route for EFFC production. MIEC is basically responsible for the performance of EFFC. EFFC with only one homogenous layer Nano-composite material comprises upon ionic and electronic conductors which will overwhelm the mechanically and chemically compatible issues. The designed material was examined experimentally and theoretically. The single homogenous layer consist upon mixed conducting Nano-composite material certifies the better performance, high efficiency and reliability. Diverse electrochemical measurements are used to investigate the performance and efficiency of prepared EFFC material. The conductivity of MIEC is investigated with 2 probe and 4 probe method. After that, the mixed conductivity was separated out with the help of ion blocking and Heb-Wagner method. These two techniques were used to study the ionic and electronic conductivity of MIEC. Similarly, the optical, mechanical, vibrational, structural characteristics and important parameters were investigated with the help of multiple techniques The working and electrochemical performance of prepared EFFC was studied at Nano level to explain the working principle of as prepared EFFC.
