Title Proper : MODELING, HEAT TRANSFER AND SYSTEM INTEGRATION FOR A 4KW REGENERATIVE PEM FUEL CELL SYSTEM
Note : This document is digital این مدرک بصورت الکترونیکی می باشد
Abstract : Fuel cells generate approximately as much heat as useful electricity,while electrolyzen convert approximately half the electrical energy input to heat. Thisstudy focuses on the rejection of the heat generated from electrolyzer and fuel cell stacksin a hydrogen and oxygen energy storage/conversion system aimed at batteryreplacement, with the objective of keeping temperatures near optimum of approximately80 C.An overall heat balance is performed, with the stack as a control volume, and heattransfers due to the water and gas flows are estimated. Modular, scaleable, finitedifference thermal models are created. Data from actual experiments are used to helpparameterize the thermal models. For the prototype he1 cell stack, the objective is metby enhancing heat convection to the surrounding air by substituting graphite fins for steelwith triple the area, while for the prototype electrolyzer increasing the water flow rateand then cooling the bypass water are found to be most effective........-....,....-...,..tested for theQ1 PC1 bus cardBoth these projects mere sofixare des elopment efforts tonards contributing to dlfferentaspects of Roboucs and lZ1echatronics projects m the Controls and Roboucs Group..
