This paper presents the performance analysis of proton exchange membrane fuel cells (PEMFCs) and evaluation of the fuel cells by using a current density extent (D) and a steady-state error rate (S) as the steady-state performance indexes based on the effects and sensitivity of the fuel cell parameters on the polarization curve. Excluding the non-linear parts of the curve, which are the activation polarization loss and the concentration polarization loss, the steady-state performance indexes, i.e. D and S, are defined and their application for both theoretical analysis and engineering practice are discussed. The presented steady-state performance indexes have been applied for analysis and evaluation of two typical fuel cells and they are found as suitable for evaluating the performance of the fuel cells. © 2008 Australasian Universities Power Engineering Conference (AUPEC'08).
