Outline of Final Research Achievements |
The objective of the research is to clarify the water transport phenomena in polymer electrolyte membrane fuel cells (PEMFC) by means of observing inside of the cell with freezing method, and simulating water behavior with LBM method. The results of the research revealed optimal structure of Micro-Porous Layer (MPL) for water discharge control, major catalyst parameters for higher catalyst performance, and CL-MPL interface condition for the better cold start in freezing temperature. LBM simulation method was also improved to simulate water behaver inside of the complex structure in gas diffusion layer.
