... Abstract In proton-exchange membrane fuel cells, the air supply system provides desired air characteristics for the fuel cell stack, significantly affecting stack performance. This study analyzes the system by modeling and simulation responses under dynamic operating conditions. The model...

... 23 02 2010 The porous diffusion medium (DM) used in fuel cells has a complex heterogeneous structure in which both hydrophilic and hydrophobic pores coexist. The capillary flow in such a mixed-wet DM is mainly controlled by the capillary pressure and saturation relation (CPSR...

... 03 03 2009 A novel fuel cell design uses porous bed electrodes. Liquid electrolyte, with fuel and oxidizer entrained, is circulated through the electrodes. An energy balance has been done for the cell and auxiliaries. The design calls for the CO-CO 2 mixture leaving the anode...
