Title:
OXYGEN PARTIAL PRESSURE CONTROLLER AND APPARATUS FOR MEASURING OXYGEN PARTIAL PRESSURE
Document Type and Number:
WIPO Patent Application WO/2011/132791
Kind Code:
A1
Abstract:
Disclosed is an oxygen partial pressure controller that improves energy efficiency and is capable of improving oxygen discharge rate. Also disclosed is an apparatus for measuring oxygen partial pressure capable of detecting differences in oxygen partial pressure in two spaces. This oxygen partial pressure controller is provided with an oxygen pump (1) constituted by stacking in this order negative electrode platinum electrode thin films (13), (23) on porous alumina substrates (12), (22), yttria stabilized zirconia thin films (14), (24) having thicknesses that do not give rise to insulation breakdown, and positive electrode platinum electrode thin films (15), (25). This oxygen apparatus for measuring oxygen partial pressure comprises this oxygen pump (1) and an oxygen partial pressure sensor (2) with an identical structure.
