Technical Papers and Presentations

Polymer electrolyte membrane (PEM) fuel cells have attracted attention as an alternative power source in various applications such as vehicles, portable supplies, and stationary power systems. A non-isothermal PEM fuel model is developed and simulated by using COMSOL Multiphysics. Although PEM fuel cells have been expected to be extensively used as an alternative power source, there have been many technical challenges to the implementation of PEM fuel cells. One of the most important issues is water and heat management in a PEM fuel cell stack. The control of water and heat is necessary for better performance and durability of PEM fuel cells.
