| Abstract |
Researches to control water content of Polymer Electrolyte Membrane(PEM) of fuel cell are actively performed for increasing performance & durability of fuel cell. This research to control water content focused on detection of PEM impedance. In this paper, the detection unit of fuel cell impedance based on AC current impedance method is proposed. Bi-directional DC/DC converter is designed to generate AC in detection unit of fuel cell impedance. The validity of proposed detection unit of fuel cell impedance is verified by test results in the fuel cell stack and FCEV. |
