In this study, 3-cell stack fuel cell power technology was developed for charging superconducting coil. It was found that the performance of the fuel cell stack increased depending on the number of activation. In addition, the flow rates of hydrogen and air supplied to 3-cell stack was adjusted because of a large difference in membrane electrode assembly (MEA) characteristics depending on its location. As a result, it was confirmed that it was possible to apply current to the superconducting coil from about 15 to 33 A by changing the variable resistance, and it was confirmed that the voltage difference between fuel cell cells could be overcome through sufficient control of fuel supply.
