Abstract :
This paper deals with the water and thermal balance in Proton Exchange Membrane(PEM) fuel cell stack through the water state calculation and thermodynamic analysis. A reasonable assumption is made by analyzing the experimental result, which assumes that the liquid water generated in fuel cell stack is removed through cathode channel and the gas at both gas channel outlet is water saturated. A new approach for water state and thermodynamic analysis is proposed, which can be used for fuel cell stack at dynamic or steady operation condition without the necessary to investigate the water transfer phenomena in proton exchange membrane.
