ABSTRACT

Worldwide researches are going on to find a suitable alternate fuel. Hydrogen is declared as an alternate fuel and accepted as an environment friendly fuel. Addition of hydrogen with existing IC engine fuels results more fossil fuel saving and it also reduce the emissions. But the storage and handling of hydrogen in movable vehicle is the major problem. To overcome the hydrogen handling problems, On-Board hydrogen production and utilization at the generation point is studied. In this study, Electrolytic Cell developed with nano pulsed power circuit. In order to generate H2/O2 by Electrolysis processes, existing vehicle maximum onboard voltage   12 volts used as input source and studied NaOH concentration varied from 0.5-15 g/L and pH variation between 12-12.9, the supply gate  triggered by an input frequency of 0-200 KHz, the maximum H2/O2 output of 2.5 mL/Sec is obtained. But the regenerative capacity of vehicle battery is 1.8 amps. So the optimum NaOH concentration is limited to 4 g/L with pH 12.5 has been observed, when supply is triggered with frequency 120 KHz, the maximum H2/O2 output of 0.58 mL/Sec is obtained for using as additive with existing fuel. Input Power for the both conventional DC and Pulsed power DC analyses and found that Pulsed Power Electrolysis consume less power. 96.8 % power saving is possible in Pulsed Power Electrolysis which is viable in moving vehicles that is on-board Electrolysis.

Keywords:Energy saving, Pulse power, Electrical energy conservation, Hydrogen, Nano Pulsed power.
