碩士 === 雲林科技大學 === 環境與安全工程系碩士班 === 97 === Energy depletion of the world should not be underestimated. Hydrogen is a high energy density fuel and combustion without secondary pollution and it is the best alternative energy sources for the new century. The study is to discuss the way of electrolytic hydrogen. The electrolyte is included hydrogen ions, hydroxide ions and electronics. The more ionics and electronics will be drifted away from the electrolyte. Magnetization effect the reaction of water electrolysis. The circle of stirring outside by the electrolyte can be accelerated of the reaction. Therefore this study will explore the different magnetization of electrolytic hydrogen impacts. This research set up the parameters on the electrode plate (SS, LCS, Ti and Ti-plated Pt), KOH electrolyte concentrations (5 and15 wt%), current density (3.3, 6.5 and 13.0 mA/cm2), magnetic field strength (0,200,600, 1000, 1400 and 1800G), electrolyte temperature of 25 ± 2 ℃, total electrolysis time of 10 min, and to add different electrolytes to find better parameters and to assessment the gas production rate and hydrogen concentration. In this study of operating conditions are the electrolyte temperature at 25 ± 2 ℃, the total electrolysis time for 10 min, electrode plate for low carbon steel (LCS), KOH electrolyte concentration of 15%, current density of 13.0 mA/ cm2, and adding magnetic which strength is 200G synchronous and continueous to be a better environment. The gas production rate is 0.15 mL / min˙cm2, than non-magnetized to increase about 6% of gas production. By analysis of variance (ANOVA) methods showed the significant differences. Electrolyte addes FeCl2˙4H2O and NaCl, respectively, in the absence of magnetic field and electrolytic 200G environment to enhance gas production about 6% and 1%. In addition, after adding the magnetic field, the electrolytic resistance of the overall is decline about 6%. Another time in the electrolysis, it is without purification by the second action with a cation exchange membrane (MC-3470) or proton exchange membrane (N-117), which will be effective from the purity of hydrogen about 67% to about 100%, and the process does not affect the efficiency of electrolysis.
