【摘要】：以90 d贮藏期的老土豆、新鲜土豆为电解质,并基于Cu、Zn作为正负极材料制成Kcel为6 cm的土豆电池,运用传感器技术研究不同贮藏期和酶活性对土豆电池供电性能的影响。结果表明,新老土豆电池的生物电性能随土豆组织的盐桥电导率、酶活性发生明显变化。首先,新鲜土豆组织较老土豆组织具有更大的盐桥电导率,其生物电性能更好;另一方面,温度对老土豆电池生物电性能的影响出现提前现象,老土豆电池的开路电压二次峰值分别出现在30、50℃,而新鲜土豆电池的开路电压二次峰值分别出现在40、60℃,这可归结于老土豆的酶活性低于新鲜土豆的酶活性;除此之外,新老土豆电池均呈现出双电层电容器的储能与放电特征。
[Abstract]:Potato cell with 6 cm Kcel was prepared by using 90 days old potato and fresh potato as electrolyte. The effect of different storage period and enzyme activity on the power supply of potato battery was studied by means of sensor technology. The results showed that the bioelectrical properties of the new and old potato cells changed significantly with the salt bridge conductivity and enzyme activity of potato tissue. First, fresh potato tissue has greater salt bridge conductivity and better bioelectrical properties than old potato tissue; on the other hand, the effect of temperature on bioelectrical properties of old potato cells appears to be in advance. The second peak of the open circuit voltage of the old potato battery appeared at 30 鈩，
