Resumen:
This paper presents the design, implementation and testing of a temperature control for
a laboratory PEM fuel cell stack work bench intended for evaluation of experimental MEAs.
The controller design is based on a thermal model of the fuel cell stack developed by the
authors. The model is extended to the complete temperature range by considering
a nonlinear description of the heating resistances. Its parameters are experimentally
adjusted and its accuracy is validated in all the temperature operating range. Then, the
temperature control is developed, using a proportional-integral structure with anti-windup
features. It is implemented in a PC connected to an ad-hoc equipment of acquisition and
control, that drives distributed cycles actuators to energize two heating resistances. The
controller proved to be capable of regulating the stack temperature in a wide operating
range, while eliminating the ripple typical of ON-OFF actuators. Finally, experimental
results of closed loop operation are presented, demonstrating the good performance of the
proposed control set up and thermal model.
