| Research Abstract |
The objective of the research is to clarify the transport phenomena in polymer electrolyte membrane fuel cells (PEMFC) by means of observing inside of the cell with freezing method, measuring current density distribution, and simulating water behavior with LBM method. The results of the research revealed detailed functions of GDL and MPL layers on the water transport, major parameters controlling the performance in the catalyst layers, freezing phenomena in cold starts, and optimal configurations of gas channels for the water discharge.
