Abstract:
Periods of transient operation during start-up, shut-down, and sudden load changes are
characteristic and ubiquitous to all power producing devices. During these critical peri-
ods, fuel cell systems rely on monitoring and controlling devices and methodologies. In
this talk we present how simple model-based control, optimization and estimation tech-
niques can be used to improve the performance and robustness of Polymer Electrolyte
Membrane (PEM) fuel cells. First, fundamental limitations in controlling the reactant
flow of power-autonomous fuel cells will be discussed. These results provide insight on
practical control strategies and calibration of fuel cell hybrid electric vehicles. Optimiza-
tion tools will then be used to determine the required fuel cell-battery sizing (hybridiza-
tion level) and the associated trends in fuel economy. Finally, we focus on the water
