OXYGEN GENERATION APPARATUS AND METHOD

摘要

An oxygen generator for an oxygen-generation apparatus has a proton-conducting membrane (60), a cathode (50) contacting a first side, or cathodic side, of the membrane, an anode (70) contacting a second side, or anodic side, of the membrane, and a source of water for supply to the membrane. In use, an electrolysis voltage applied between the cathode and the anode causes electrolysis of the water to generate oxygen gas at the anode. Atmospheric oxygen, i.e. oxygen in the air, is substantially prevented from coming into contact with the cathode. For an acidic proton-conducting membrane this substantially prevents the formation of hydrogen peroxide at the cathode.
