Sažetak
The paper presents the results of a trade-off study of an automotive fuel cell propulsion system equipped with a fuel reformer. Based on a set of fuel cell polarization curves determined experimentally by runing a prototype fuel cell stack at a variety of operating pressures and temperatures, a numerical steady state model was used to determine the optimal operating pressure and temperature. In general, higher operating pressure results in higher parasitic power requirements, which partially may be offset by an expander. A combination of high pressure (308 kPa) and relatively low operating temperature (60°C) has been selected based on this trade-off analysis. The resulting system is 33% efficient at full power and 38% efficient at partial load (25% of nominal power).
