    摘要： A hydrogen/oxygen gas generating system includes a deionized water container and a cell for water electrolysis having anode and cathode compartments, the cell being submerged in deionized water in the container. Oxygen gas generated in the anode compartment is channeled to an oxygen gas separating chamber defined in the container at its top whereas hydrogen gas generated in the cathode compartment is channeled to a gas/liquid separator. The pressures of these gases are detected, and in accordance with the detected gas pressures, a first gas piping line for delivering oxygen gas outward from the oxygen gas separating chamber and a second gas piping line for delivering hydrogen gas outward from the separator are controlled such that the differential pressure between the gases may fall in a limited range. Water level in the oxygen gas separating chamber and water level in the gas/liquid separator are detected, and the detected levels are utilized to control the pressures and the supply of deionized water into the container. The system can generate hydrogen and oxygen gases of high purity under high pressure in a safe manner without a need for gas compressors.
