Steady State Power Properties Analysis of Parasite System for A PEM Fuel Cell Engine 2005-01-2212
In this paper, a parasite system power empirical model of a PEM fuel cell engine suitable for the study of fuel cell vehicle simulation is developed by fitting the experimental data with quadratic polynomial. The assumption of the model is that the fuel cell stack is in steady-state condition. The properties of the parasite system power are analyzed. Based on the analysis of the properties of the parasite power, two parameters--- stack power factor RAS and FCE power factor RAF are introduced to evaluate the quality of the stack and the fuel cell engine. Moreover, the parasite system power model is verified by test data. The result indicates that the model is accurate to reflect the static performance of the parasite system. The advantage of the model is that its structure is simple, and its parameters are easy to be obtained. It is easy to apply to the study of fuel cell vehicle simulation.
