| Popis: | 105 In this work, we develop a simple design for modularizing PEM fuel cell stacks to facilitate disassembling and maintenance of a fuel cell stack. In addition, reducing the thickness of the bipolar plate to increase the volumetric and specific power density. This new design avoids the disadvantage of other modularization design that usually increase quite a lot the volume and weight of the fuel cell stack. The interface pressure and electrochemical impedance are measured for stacks consist of different number of cells to study the influence of this new modularization design on fuel cell performance. Effects gas flow resistance and interfacial electrical resistance are investigated. The results show that this new modularization design does actually decrease the disassembling and maintenance time, while retain almost the same value of contact impedance and fuel flow resistance as un-modularized stack. It proves that the modularization design in this work is successful and practical. |
