Impact of varying structures and surface treatments of gas diffusion layers (GDL) on water management processes within the lifespan of PEM f
Water inventory inside a PEMFC significantly influences the cell's performance and lifespan. Microporous (MPL) coated Gas diffusion layers (GDL) facilitate a uniform distribution of the reactant gases to the catalyst sites and removal of the excess water accumulated inside the cell. The balanced water management will help to prevent the blockage in the gas diffusion paths. In this study, we will investigate the influence of the structure and the surface treatment variation of gas diffusion layers (GDL) on water management processes and performance within the lifespan of PEM fuel cells and the scale up from small cells to cells of full channel length. For different GDL materials, the cell¿s water management will be investigated at both the Beginning of Life (BOL) and the End of Life (EOL). By performing the measurements, we want to improve the water inventory and thereby the performance of the fuel cell. The scale up capability of the cell to full size channel length shall be investigated by performing measurements both with the small scale cell and the full channel length cell. By performing these measurements, we want to improve the methodology of measurements.
