Temperature and humidity regulations of an open-cathode PEM fuel
cell with balance of plant (BOP) are developed in this study. The axial fan, a bubble
humidifier, set of solenoid valves and a controller are used to perform temperature
and humidity control simultaneously. A fuzzy controller is designed, and it
shows its superiority in real-time controlling for strong non-linear dynamical fuel
cell system. The axial fan speed is used for temperature control and solenoid
valve on/off signal of the bubble humidifier is used for humidity control. The axial
fan speed is controlled to keep the fuel cell temperature within the desired point.
Meanwhile, the bubble humidifier is utilized to moisture hydrogen to manage the
water content of membrane. The results show that the proposed fuzzy controller
effectively increases the output power of 10% for a PEM fuel cell.
