Fuel cells are an effective and environmentally-friendly energy conversion device. For a fuel cell (hydrogen and oxygen) the practical application with appropriate materials for hydrogen storage and auxiliary power unit (supercapacitor) is very important. Major constraints associated with this device is its high cost. This study explores the use of carbon nano-materials as fuel cells, Super capacitors and solution of materials for hydrogen storage. In this research work, the hydrogen-oxygen fuel cell using low-cost materials development. Novel porous ceramics are used as electrode substrates. Synthesis of turpentine by using chemical vapor deposition of the different forms of carbon nanomaterials (beads, fibers and nano-tubes)-low cost of natural precursors. These nano-materials are used as catalyst support. Different single/bi-metal/metal alloy catalysts for the oxidation of hydrogen (Platinum, Palladium, nickel, cobalt, iron, and Sn) and the oxygen reduction (silver, Platinum, Palladium, manganese, magnesium, nickel, cobalt, aluminum, copper, Ce, and Fe). Preparation of urea catalyst decomposition method of reactive oxygen (silver, iron, cobalt, copper and ceria) is used both as a catalyst and as a catalyst for the growth of carbon nanotubes. Synthesis of carbon nano-materials are also for storing an electrochemical potential (double-layer supercapacitor), as well as waste hydrogen from turpentine and Agriculture (plant waste and sugar cane husk). Different acids, alkali, all for purification and activation of carbon nano-materials. Before and after the activation of the carbon nano-materials are studied. In order to study the elemental composition of surface morphology and different carbon materials, SEM,TEM,X-ray diffraction and x-ray fluorescence analysis. In order to measure the conductivity electrode relative to temperature changes recorded by van de-PauwThe resistivity method. Fuel cell electrode electrochemical performance of hydrogen dissociation is determined by measuring the voltage, half and whole-cell battery IE and timing characteristics. Super capacitor, capacitance measurement of carbon nano-materials by cyclic voltammetry and constant-current charge-discharge experiments. Hydrogen adsorption studies by physical absorption, Raman, TGA/DTA and CHNO analysis completed. Differences between carbon nanomaterials, carbon nanotubes are considered alkaline fuel cell (AFC) optimum electrode materials. Voltage respectively obtained by hydrogen and oxygen dissociation voltage of 96.5\% theory 98.2%. From the results obtained in this study indicate that nickel-Tin (85:15) is an efficient hydrogen storage electrode and Ag-Mg lines (70:30), silver, iron-copper (83:13:4) is the best, because the oxygen electrode. 384 Ma maximum current density of 262.3 milliwatts/square centimeter/square centimeter, power records these electrodes, respectively. Records obtained from the sugar cane plant wastes of carbon nano-materials 217.7F/g capacitor. Study on the adsorption of hydrogen on metal (h-activate) CNT and inserted metal dispersion of nano-carbon materials. Gain Pd-Sn obtained from sugar cane plant waste dispersion of hydrogen adsorption in carbon nano-materials by 11.95% and 4.83%desorptivity. Research results show that based on carbon nanotube material that could be used for fuel cells, Super capacitors and cost-effective hydrogen storage solutions.
