Abstract

PURPOSE:To obtain the humidity in real time and at high precision by calculating the humidity in the cell exhaust gas based on the measurement values of the oxidizer component gas flow at the cell inlet, the oxygen density at the cell outlet, and the load current of the cell. CONSTITUTION:Consumption quantities of oxygen and carbon dioxide are determined via the equation I and equation II based on the data of a load sensor. Flows of oxygen, carbon dioxide, and other gases are determined based on the data of flow sensors. The oxygen gas consumption quantity determined via the equation I is subtracted from the oxygen gas quantity at the cell inlet to obtain the oxygen density y' in the dry state at the outlet. The oxygen density y(%) in the wet state is determined by a zirconia-oxygen sensor. The humidity x(%) is obtained via the equation III.
