INTERNAL-RESISTANCE MEASURING DEVICE FOR RESPONSE-DELAY TYPE FUEL CELL

摘要

The present invention provides a measuring device that considers response delay to power load fluctuations and automatically evaluates power generation characteristics of response delay type fuel cells with good reproducibility and effectively cultivates and nurtures microorganisms related to power generation. A potentiometer / galvano start 5 is connected to the microbial fuel cell 7 as an example of the response delay type fuel cell, and an automatic measuring device 3 is connected to the potentiometer / galvano start 5. . The automatic measuring device 3 has a program function and measures the internal resistance of the microbial fuel cell 7 at a set timing. The measurement of the internal resistance instructs the automatic measuring device 3 to change the current value flowing through the potentio / galvano start 5 to the microbial fuel cell 7, and after the voltage value of the microbial fuel cell 7 is stabilized, The step of measuring and recording the current value and the current value is repeatedly performed while the current control value is changed step by step.
