Proc. ASME. FUELCELL2006, ASME 2006 Fourth International Conference on Fuel Cell Science, Engineering and Technology, Parts A and B, 917-924, June 19–21, 2006
Paper No: FUELCELL2006-97217
... It is important to elucidate the transient characteristics of polymer electrolyte fuel cells (PEFC), especially when PEFC is applied to relatively small-scale power applications where it will be subjected to a wide range of loads, and may have frequent starts and stops. In addition, the water...

Paper No: FUELCELL2006-97070
... Performance of polymer electrolyte fuel cells (PEFCs) is highly dependent on water content of the membrane and a humidification scheme becomes a necessity to operate PEFCs at a high efficiency. However, conventional humidification schemes require external humidifiers, which are usually bulky...

... mechanisms with enhanced optical access of both side and top views of the flow channel of a simulated H 2 PEFC. A telecentric lens and 5 mm by 5 mm prisms embedded in the flow channel side walls were used for the first time to measure droplet receding and advancing surface angles in an enclosed flow channel...
