Abstract

A simple and efficient apparatus for producing hydrogen and oxygen is disclosed, wherein resistance to the flow of deionized water, oxygen gas, and hydrogen gas does not increase, and the amount of electric energy required for electrolysis can be reduced. A bipolar-type apparatus for producing hydrogen and oxygen, wherein a main water feeding path is formed in the approximate center of electrode plates in the axial direction, and an anode chamber and a cathode chamber are formed on opposing surfaces of the electrode plates to store porous conductors. A secondary water feeding path for the anode chamber directs water from the main water feeding path to the anode chamber. On the cathode side of the apparatus, a hydrogen gas collecting chamber is formed, a plurality of radial hydrogen gas paths are formed from the cathode chamber to the hydrogen gas collecting chamber, and a hydrogen gas discharging path are formed to axially hydrogen gas collecting chambers in each electrode plate. On the anode side of the apparatus, an oxygen gas path is formed from the anode chamber to the oxygen gas collecting chamber, and an oxygen gas discharging path is formed to axially connect to the oxygen g…
