Abstract

Tests were carried out to examine the possible use of galvanic lead-gold oxygen fuel cells for meassuring oxygen partial pressure in hyperbaric conditions and their possible application in underwater breathing apparatuses. Three types of sensors were exposed to total pressure variations up to 600 kPa and with variations in oxygen partial pressure from 0 to 240 kPa. The tests were carried out in a pressure chamber with dry gas and under isothermic conditions. Every sensor was compressed a total of 14 times. No effect of total pressure or inert gas pressure on the sensor signals were seen in any of the tested sensors, but One sensor showed non-linearites with high oxygen partial pressures.
