Abstract

A hydrogen/oxygen supply system which has an electrolytic cell separated into an anode side and a cathode side by a solid electrolytic membrane, which is so constituted as to supply pure water to the electrolytic cell to produce hydrogen on the cathode side and oxygen on the anode side and enable at least one of the hydrogen and oxygen to be supplied to an application location, and which comprises a first pressure detecting means able to detect the pressure of the hydrogen supplied via the cathode side of the electrolytic cell, a second pressure detecting means able to detect the pressure of the oxygen supplied via the anode side of the cell, a differential pressure detecting means for comparing a pressure detection signal obtained at the first pressure detecting means with that obtained at the second pressure detecting means to produce a specified differential pressure signal, a first relief mechanism able to regulate the pressure of the hydrogen based on the differential pressure signal, and a second relief mechanism able to regulate the pressure of the oxygen based on the differential pressure signal, a pressure on the anode side and a pressure on the cathode side in the electrolytic cell being regulated by using the first and second relief mechanisms.
