ABSTRACT:
An oxygen concentration controlling element where the shortest distance between the anode and cathode separated by a solid electrolyte film is set not larger than 50 .mu.m, thereby to accelerate the back-diffusion of water generated in the cathode to the anode and dispense with a tank or a pump for supplying water to the anode. An oxygen concentration or humidity controlling apparatus where a photoelectric element is disposed at an opening of a to-be-controlled space to the atmospheric air and the electric energy from the photoelectric element is accumulated in a secondary battery, thus realizing space-saving apparatus which can operate continuously though the power is turned off, and a humidity controlling apparatus functioning both as a humidifier and as a dehumidifier.
