In the first part of the research work, an electrolyzer (10.16 cm dia and 24.13 cm height) to produce hydrogen and oxygen was constructed for single slice O2H2 fuel cell using cation exchange membrane. The electrolyzer performance was tested with 23 NaOH, 30 NaOH, 30 KOH and 35 KOH electrolyte solution with current input 4 amp and 2.84 V from the rectifier. Rates of volume of hydrogen produced were 0.159 cm3sec, 0.155 cm3sec, 0.169 cm3sec and 0.163 cm3sec respectively from 23 NaOH, 30 NaOH, 30 KOH and 35 KOH solution. Rates of volume of oxygen produced were 0.212 cm3sec, 0.201 cm3sec, 0.227 cm3sec and 0.219 cm3sec respectively from 23 NaOH, 30 NaOH, 30 KOH and 35 KOH solution (1.5 L). In spite of being tested the increased concentration of electrolyte solution, the gas rate does not change significantly. Therefore, inexpensive 23 NaOH electrolyte solution was chosen to use as the electrolyte in the electrolyzer. In the second part of the research work, graphite serpentine flow plates, fiberglass end plates, stainless steel screen electrodes, silicone rubbers were made to assemble the single slice O2H2 polymer electrolyte membrane fuel cell (PEMFC).
