Flow field optimization plays a vital role in improving the output performance of proton exchange membrane fuel cells (PEMFCs), especially at high current density. A streamline dot flow is proposed this study to enhance mass transfer reactant gas and compared it with parallel, rectangular dot, rhombic fields. The influence tail length block on further analyzed. results show that uniform distrib...

Commercialization of proton exchange membrane fuel cells can only materials provided its performance is closely related to existing technologies useful in commercial application. Other critical parameters like the utilization cheaper should be taken into account during manufacturing cell. A key component cell that has direct correlation flow plate. The weight coupled with cost revolves around p...

The use of a dual-layer cathode catalyst layer improves the performance proton exchange membrane fuel cells. To generate single and layers between gas diffusion media electrolyte, two commercial carbon-supported platinum catalysts with either high microporosity carbon (Ketjen Black EC-300J) or low porosity (XC-72 Vulcan carbon) are utilized. We discovered that boost maximum power cells regardle...

The degradation seriously affects the durability and cost of proton exchange membrane fuel cell (PEMFC). This article presents a novel model-driven method based on frequency-domain Kalman filter (FDKF) voltage model to predict PEMFC in frequency domain. advantage proposed FDKF is that it can process data groups; thus, computation time be greatly reduced with high accuracy. Two experiments under...
