A104 インライン型極細熱電対の開発 : PEFC内部の水挙動解析に資する取組(OS5 水素・燃料電池(1))

抄録

To reduce PEFC accessories, especially for water management, that account for 50% of FC system cost, it is effective to simplify the accessories based on understanding water behavior in cell In this study, we developed a noble method of measuring temperatures in a cell with the array of thin thermocouples (φ 50 um) Temperature measurement is useful to comprehend the water behavior through the relationship between the water behavior and temperature We fabricated an in-line thin thermocouple, which is specific to this measurement Here, butt-welding of the thin thermocouples was executed with a capillary tube in inner diameter φ 60 jam In addition, polyimide film coated the thermocouples in its thickness of 2 |im The thermocouple had electric insulation resistance of 0.5 kΩ, and it was not enough to measure the temperature in cell
