This document summarizes an experimental study on the effects of humidification temperature on the performance of a proton exchange membrane (PEM) fuel cell. The study found that increasing the humidification temperature from 40°C to 80°C resulted in increased voltage and power output from the fuel cell. Specifically, increasing the humidification temperature led to a 38% increase in voltage at a current density of 1.2 A/cm2. The highest performance was achieved with a humidification temperature of 80°C and hydrogen and oxygen flow rates of 3.0 ml/s and 6.0 ml/s respectively. The results indicate that providing sufficient humidification, including at higher operating temperatures, can improve PEM fuel cell performance.
