Hydrogen and oxygen gas generating system

A hydrogen and oxygen gas generating system comprising

• a water electrolysis cell having anode and cathode compartments separated from one another by a diaphragm wherein deionized water is electrolyzed to generate oxygen and hydrogen gases in the anode and cathode compartments, respectively,
• an oxygen outflow pipe connected to the anode compartment of said electrolytic cell for channeling oxygen gas resulting from electrolysis upward from the anode compartment,
• a hydrogen outflow pipe connected to the cathode compartment of said electrolytic cell for channeling hydrogen gas resulting from electrolysis upward from the cathode compartment,
• a container which can be filled with deionized water, surrounding the electrolytic cell and supporting the cell submerged in deionized water, said container including a partition for dividing an upper portion of said container into oxygen and hydrogen compartments in a fluid tight manner to prevent any gas leakage therebetween, upper ends of said oxygen and hydrogen outflow pipes opening in said oxygen and hydrogen compartments, respectively,
• a deionized water feed means for feeding deionized water into said container,
• said cell further having a communication port at the bottom of the anode compartment for communication of deionized water between the cell interior and the container interior,
• a first level detector means for detecting the level of water in said oxygen compartment,
• a second level detector means for detecting the level of water in said hydrogen compartment,
• a first gas piping line for delivering outward the oxygen gas accumulating in an upper space of said oxygen compartment, said first gas piping line having one flow controller for controlling the flow rate of outward oxygen gas flow and said first gas piping line including a branch for leaking oxygen gas and another flow controller in the branch for controlling the flow rate of leaking oxygen gas flow,
• a second gas piping line for delivering outward the hydrogen gas accumulating in an upper space of said hydrogen compartment, said second gas piping line having a flow meter for measuring the flow rate of hydrogen gas,
• a gas flow rate control means for controlling at least one of the flow controllers of said first gas piping line in accordance with a measurement of the flow meter of said second gas piping line and controlling the other flow controller in the branch of said first gas piping line in accordance with the water level detected by said second or first level detector means,
• said deionized water feed means being actuated to feed deionized water into said container in accordance with the water level detected by said first or second level detector means,
• a DC power source for supplying electric power to said electrolytic cell, and
• a power regulator coupled to said DC power source for controlling the power supply to said electrolytic cell in accordance with the pressure detected by a gas pressure detecting means in said second or first gas piping line to control the gas pressure.
