Proton exchange membrane fuel cell measurement condition optimization and effects of different key materials
PEMFCs are a favoured alternative for their clean emissions, high energy density and superior efficiency compared to other energy generation sources. However, the mechanisms involving the different components in the fuel cell are very complicated and much research is still needed to better understan...

PEMFCs are a favoured alternative for their clean emissions, high energy density and superior efficiency compared to other energy generation sources. However, the mechanisms involving the different components in the fuel cell are very complicated and much research is still needed to better understand the ways to minimize the associated losses in the fuel cell while maximising its lifespan. Hence, this project aims to examine the effects of how each operating parameter affects fuel cell performance and select the best parameters for optimal performance. In this report, oxygen flow rates, reactant backpressures, cell and humidification temperature, Gas Diffusion Layers (GDLs) and Catalyst-Coated Membranes (CCM) were compared. In general, it was found that oxygen backpressure, cell temperature, type of GDL and CCM were of significant importance in dictating cell performance. Along the way, activation process was also found to be rather important in affecting the cell performance.
