In this study, we propose a configuration of partially blocked oxidant channel with baffle plate(s) transversely inserted in the cathode channel and their effect on the oxygen transport and fuel cell performance is investigated. In order to investigate the effects of the selected shape, size and the number of baffles on the oxygen transport in the gas diffusion layer (GDL) and fuel cell performance a numerical modeling is carried out in 27 cases. With the consideration of both maximum oxygen concentration in the GDL and reasonable pressure drop criterions, the results indicate that in all cases, an increase in baffle height is more effective than an increase in number of baffle plates. Also, installing many large rectangular baffles seem quite appropriate, but when there is restriction in securing pressure in fuel cell, installing the semicircle baffle is better than the rectangular one.

Thermal behavior inside fuel cells plays a significant role in fuel cell performance and durability. Internal temperatures of a proton exchange membrane (PEM) fuel cell govern the ionic conductivities of the polymer electrolyte, influence the reaction rate at the electrodes, and control the water vapor pressure inside the cell. Temperature gradients also influence mass transport due to phase-change-induced flow and thermo-osmosis. Many techniques developed for studying in situ temperatures such as thermocouples sensors either disrupt fuel cell performance or carry unknown accuracy. The objectives of this research are to design and construct thermal sensors based on the principles of the lifetime-decay method of phosphor thermometry to measure temperatures of cathode gas diffusion layer inside a PEM fuel cell with minimal invasion. The sensors also demonstrate the possibility of detecting water droplet formation in the flow channels qualitatively making it possible to experimentally relate local temperature distribution with liquid water formation. Further development is required in order to increase the accuracy and utility of the sensors before conclusive testing can be performed.
