Abstract
The performance of fuel cells is influenced by numerous factors, with operating temperature being particularly crucial. This study aims to analyze fuel cell performance across various temperatures and optimize operational parameters at the optimal temperature to enhance both performance and lifespan. The research identifies 69.9 °C as the optimal temperature for fuel cells, with an efficient operating temperature range of 60–80 °C. Additionally, the optimal flow rate range is determined to be 1000–1600 ml/min. It is also noted that the influence of back pressure on fuel cell performance diminishes when it exceeds 2.5 bar. Furthermore, this study employs a Gaussian process regression model to optimize fuel cell performance under different combinations of temperature, flow rate, and back pressure. The regression analysis predicts that the optimum operating temperature is 71 °C, with an optimal back pressure range of 0.9–1.4 bar and a flow rate range of 1310–1600 ml/min.
期刊介绍：
Ionics is publishing original results in the fields of science and technology of ionic motion. This includes theoretical, experimental and practical work on electrolytes, electrode, ionic/electronic interfaces, ionic transport aspects of corrosion, galvanic cells, e.g. for thermodynamic and kinetic studies, batteries, fuel cells, sensors and electrochromics. Fast solid ionic conductors are presently providing new opportunities in view of several advantages, in addition to conventional liquid electrolytes.
