This computational study focuses on the IV characterization (currentvoltage-power) of a 1 kW-24 Vdc proton exchange membrane fuel cell (PEMFC) stack. Leveraging an online MATLAB package, we simulated the performance of a 42-cell stack, incorporating air and hydrogen flow rates. The simulation parameters included a stack efficiency of 46%, an air flow rate of24001pm, and an operating temperature of 55 °C. Our objective was to comprehensively investigate the IV characteristics of the PEMFC over a 1-hour duration. The results demonstrate a linear relationship between current and voltage, with a maximum power output of 2 W and a voltage range of Oto 45.5 V. The study contributes valuable insights into PEMFC dynamics, offering a computational approach for characterizing and optimizing performance. This work lays the foundation for further exploration of PEMFC behavior under varying conditions; paving the way for advancements in fuel cell technology. [ABSTRACT FROM AUTHOR] |
