Thermodynamic Analysis of the Performance of an Irreversible PEMFC Changjie Li, Ye Liu, Zheshu Ma* College of Automobile and Traffic Engineering, Nanjing Forestry University, Nanjing, 210037, China *E-mail: mazheshu@njfu.edu.cn Keywords: PEMFC; irreversible model; thermodynamic performance; operating conditions; overpotential voltage Abstract.
The cause of ohmic potential is the impedance of the ionic flow in the fuel cell electrolyte and the impedance of the electron flow in the electrode material, which can be represented as[10-12]: Vohm=(i+ileak)Rohm=(i+ileak)(Relec+Rionic) (3) Here Relec is the resistance of the bipolar plate, interface contact and end connections and other battery components that the electrons flow through.
