Temperature fuzzy control of movable power source about proton exchange membrane fuel cells

Movable power source of proton exchange membrane fuel cell is an important research direction of current fuel cell research field, and becoming a rising research hot spot, its temperature control influences the cell performance of movable power source greatly. This paper studied temperature control of proton exchange membrane fuel cell used by multi-variables fuzzy inference and the fuzzy logic control theory in the view of technology application, established the temperature fuzzy control system of movable power source about proton exchange membrane fuel cell, effectively solved the proton exchange membrane fuel cell temperature control problems caused by time-change, long-hysteresis, uncertainty and strong-coupling. The computer simulation indicates that it is reasonable and effective, and meets its require of temperature control characteristic.
