Abstract
New type amperometric oxygen sensors using a NAFION membrane were investigated for monitoring oxygen partial pressure at room temperature. The sensor element finally constructed had a structure in which an electrochemical cell was combined with a hydrogen-generation system and a gas-diffusion layer. Its sensing current under the short-circuit condition was found to vary linearly with the oxygen partial pressure. The 90% response time was about 3 min at 25 °C.Keywords
