    • A method utilizing the resistance of the electrolytic membrane of a fuel cell is known conventionally as a method for detecting abnormality occurring in the fuel cell. As shown on FIG. 4, resistance of the electrolytic membrane increases as the temperature thereof decreases or the moisture content thereof decreases (i.e. dry state), and decreases as the temperature increases or the moisture content increases (i.e. wet state), and thereby it was difficult to judge whether a deterioration in performance or a simple drop in performance has occurred by simply detecting an increase in resistance. A criterion for judging a deterioration in performance of a fuel cell based on the resistance of an electrolytic membrane is thereby set higher as the electrolytic membrane approaches a dry state and temperature thereof decreases and set lower as the electrolytic membrane approaches a wet state and the temperature thereof increases. Consequently, a deterioration in performance of a fuel cell can be judged easily regardless of the operating state thereof.
    • 利用燃料电池的电解质膜的电阻的方法通常被认为是用于检测在燃料电池中发生的异常的方法。 如图所示。 如图4所示,随着温度降低或水分含量降低(即干燥状态),电解质膜的电阻增加,随着温度升高或湿度增加(即湿润状态)而降低,因此难以判断电解质是否 通过简单地检测电阻的增加,发生性能的恶化或性能的简单降低。 由于电解质膜接近干燥状态并且其温度降低并且随着电解质膜接近潮湿状态而降低,所以基于电解质膜的电阻来判断燃料电池的性能劣化的标准被设定得更高 其增加。 因此,能够容易地判断燃料电池的性能的劣化,而与其工作状态无关。
