abstract = {Gas purging process of cathode side during the shut-down
procedure of a polymer electrolyte membrane fuel cell
(PEMFC) system is of great importance for a successful cold
start. This paper proposes a study on the modeling and
control of the cathodic gas purging process, whose main
purpose is to remove liquid water in the gas diffusion layer
(GDL) and the membrane. The water removal process can be
divided into three steps, which are called (a) the
through-plane drying of the GDL, (b) the in-plane drying of
the GDL, and (c) the vapor-transport from the membrane. A
nonlinear model is firstly developed to describe the water
removal process in the GDL and the membrane. It includes a
one-dimensional three-step purging sub-model and an energy
consumption sub-model considering the properties of the air
compressor. Experiments are carried out to validate the
water-remove model by using the membrane HFR. An optimal
constant purging control strategy that minimizes energy
consumption during the cathodic purging process is designed
based on the model and verified in simulation.},
