The operating parameters have an important impact on the performance of a proton exchange membrane fuel cell (PEMFC). This paper investigates experimentally and numerically the cell temperature and relative humidity which have a significant influence on the PEMFC current density. These parameters are adjusted simultaneously and dynamically during operation. A 50 cm(2) active area single-cell PEMFC with serpentine flow channel was studied. In order to confirm the experimental measurements, a mathematical model was established using the MATLAB package program and the results were compared. According to both experimental and mathematical model results, adjusting the operation parameters instantly according to the current value produced by the cell had a positive effect on the cell durability and performance.
