The problem of oxygen starvation in fuel cells coupled with air compressor saturation limits,
is addressed in this paper. We propose using a hybrid configuration, in which a bank of …

Transient performance is a key characteristic of fuel cells, that is sometimes more critical
than efficiency, due to the importance of accepting unpredictable electric loads. To fulfill the …

Management of the water and heat ejected as byproducts in an operating PEM fuel cell
stack are crucial factors in their optimal design and safe operations. Models currently …

A compressor-based air supply system in a fuel cell is susceptible to saturation during fast
transients in load. Aggressive control of the air compressor may result in compressor surge …

Two primary parameters stand out for characterizing fuel cell system performance. The first
and most important parameter is system efficiency. This parameter is relatively easy to …

System-level modeling and control strategy development for a fuel cell hybrid vehicle
(FCHV) are presented in this paper. A reduced-order fuel cell model is created to accurately …

This paper explores different hybridization levels of a vehicle powered by a polymer
electrolyte membrane fuel cell stack. The energy buffer considered is a lead-acid type …

Although a variety of design and control strategies have been proposed to improve the
performance of polymer electrolyte membrane (PEM) fuel cell systems, temporary faults in …

Recent trends and advances in hydrogen/air Proton Exchange Membrane Fuel Cells
(PEMFC) are incorporated into a dynamic control oriented model. This type of model is …

This paper proposes a non-linear state-space dynamic model for planar proton exchange
membrane fuel cell (PEMFC). Our objective is the realization of a model that evokes a more …
