贮藏期与酶活性对土豆电池电性能的影响
Effect of storage period and enzyme activity on bioelectrical property of potato battery
摘要
Abstract
Two kinds of potato batteries based on the Cu and Zn denoted as the anode and cathode materials were fabricated by the old potatoes with storage period of 90 day and the fresh potatoes as an electrolyte,respectively.The effects of different storage period and enzyme activity on the bioelectrical properties were studied by using sensor technology for potato battery.These results indicate that the bioelectrical properties of new and old potato battery are changed with salt bridge conductivity of potato tissues and enzyme activity of potato tissues evidently.Firstly,new potato tissues possess higher conductivity of salt bridge than that in old potato tissue,performing a better bioelectrical capacity.On the other hand,there exists an advanced phenomenon for bioelectrical properties in old potato battery.The two peak values of open circuit voltage in old potato battery appear at 30 and 50 ℃,respectively.For fresh potato battery,however,these two peaks of open circuit voltage performs at 40 and 60 ℃,respectively.It can be attributed to the fact that the enzyme activity of old potato is significantly lower than enzyme activity of the fresh potato.In addition,both the new and the old potato batteries present the energy storage and the discharge characteristics that similar to electrical double-layer capacitor.关键词
