摘要: Abstract Water and heat management are the most critical issues for performance of proton exchange membrane (PEM) fuel cells. They can be provided by keeping hydrogen flow rate, oxygen cell temperature humidification under control. In this study, effects these parameters on power density which has 25 cm2 active area have been examined experimentally using anode side cathode side. Response Surface Methodology (RSM) applied to optimize operation cell. The test responses maximum output density. ANOVA (analysis variance) analyses used compute contributions various factors maximal use design shows also how it is possible reduce number experiments. Hydrogen were main varied between 2.5–5 L/min, 3–5 L/min, 40–70 °C 40–80 °C in analyses. was found as 241.977 mW/cm2.
