Trapezoidal Channel Proton-Exchange Membrane Fuel Cell Performance Study

Many factors affect the performance of hydrogen-oxygen proton-exchange membrane fuel cells; there are not only operating parameters, transmission, and electrochemistry inside the battery but also physical composition and bipolar plates. In this paper, the geometric configuration and parameters of the runner have been studied. The performance of a rectangular runner and trapezoidal runner was compared, and it was found that the performance of the trapezoidal runner was better. Therefore, the influence of the inlet angle and height of the outlet runner on the performance of the trapezoidal cross-section battery is discussed. The goal is to find a trapezoidal cross-section fuel cell with the most superior performance.
