Water management of PEM fuel cells using fuzzy logic controller system

In this paper, several control strategies for water management of proton exchange membrane (PEM) fuel cells are presented. The controllers were designed, developed and implemented in Fuel Cell Laboratory at Florida Atlantic University (FAU) in order to increase the efficiency and performance of PEM fuel cells. Two different pulsing approaches were implemented. The amplitude variations of the pulses were controlled through a regulator on the air source pump. Other parameters were tuned using computer software in conjunction with A/D, D/A, and electronic circuits. In addition, a fuzzy controller is proposed for water management of PEM based on Mamadani inference systems. The preliminary experimental results demonstrate the effective of the method.
