MICRO FUEL-CELL OXYGEN GAS SENSOR. |
摘要 |
An oxygen sensor for measuring oxygen in the ppb range. The sensor comprises an electrochemical cell. The oxygen is metered to the cathode based on gaseous phase diffusion to provide a measurement proportional to volumetric concentration. Hydrogen is metered to the anode in an amount in excess of the oxygen being reduced at the cathode. A current is generated which is linear to the volumetric concentration of the oxygen in the sample gas. The concentration of the oxygen is measured based on the current generated. |
