    • According to the present invention, SO.sub.X in the exhaust gas of an internal combustion engine is absorbed by a sulfate absorbent which absorbs SO.sub.X in the exhaust gas when the temperature is lower than a releasing temperature and releases the absorbed SO.sub.X when the temperature becomes higher than the releasing temperature. When the exhaust gas temperature increases during the operation of the engine and reaches the releasing temperature, the temperature of the exhaust gas flowing into the sulfate absorbent is further raised to a predetermined temperature by supplying fuel to the exhaust gas passage upstream of the sulfate absorbent. The ratio of SO.sub.3 in the SO.sub.X mixture released from the sulfate absorbent changes in accordance with the temperature, and takes the highest value at a certain temperature (i.e., a peak temperature). Therefore, when the exhaust gas temperature is raised above the peak temperature, the ratio of SO.sub.3 in the SO.sub.X mixture released from the sulfate absorbent decreases as the temperature increases. In the present invention, the above-noted predetermined temperature is selected in such a manner that the ratio of SO.sub.3 at this predetermined temperature becomes lower than the ratio of SO.sub.3 at the releasing temperature. Therefore, when SO.sub.X is released from the sulfate absorbent, the amount of SO.sub.3, i.e., the amount of particulate matter released into the atmosphere can be maintained at a low level.
    • 根据本发明,内燃机废气中的SO x被吸收在温度低于脱模温度时吸收废气中的SO x的硫酸盐吸收剂,并且当温度变得高于 释放温度。 当发动机运转时排气温度升高并达到释放温度时,通过向硫酸吸收剂上游的排气通道供给燃料,进一步将流入硫酸盐吸收剂的废气升温至规定温度。 从硫酸盐吸收剂释放的SO x混合物中的SO 3的比例根据温度而变化,并且在一定温度(即峰值温度)下获得最高值。 因此,当废气温度升高到高于峰值温度时,从硫酸盐吸收剂释放的SO x混合物中的SO 3比随温度升高而降低。 在本发明中,以这样的方式选择上述预定温度,使得在该预定温度下的SO 3的比例低于在释放温度下的SO 3的比例。 因此,当SOX从硫酸盐吸收剂中释放出来时,SO 3的量,即释放到大气中的颗粒物质的量可以保持在较低水平。

    • In a fuel cell system equipped with polymer electrolyte fuel cells, an alternating current generator applies an alternating current of a fixed frequency and a fixed amplitude to the fuel cells. An alternating current voltage acquisition module (combination of a filter unit and an A-D converter with a controller) extracts an alternating current component attributed to the application of the alternating current from an output voltage in a specific unit cell of the fuel cells and time-sequentially obtains a voltage value of the extracted alternating current component. A moisture state monitoring module (the controller) identifies whether the fuel cells have a moistening tendency. In the case of identification of the moistening tendency of the fuel cells by the moisture state monitoring module, an over-hydration detection module (the controller) computes a statistical value representing a magnitude of a variation in time-sequentially obtained voltage value of the alternating current component and determines that the fuel cells are in an over-hydration state when the computed statistical value representing the magnitude of the variation exceeds a preset reference level.
