摘　　要：以微机电制程制作微型燃料电池为研究基础,讨论了集电板开孔率、燃料对流方式、以及电池组装时锁紧力对性能之影响。实验结果表明,相同开孔率集电板,电池性能随集电板开孔数增加而提升;强制对流方式的单电池比较适合高电流密度输出使用,而自然对流式电池较适合低电流长时间输出使用;电池组装之锁紧力必须在不使流道结构变型的情况下增加才能有效提升其性能;由于PDMS基材有比较少的积水现象,因此PDMS基材单电池比硅基材更适合用在自然对流式微型燃料电池上。This study fabricated micro fuel cell by using the MEMS technology. A series of performance experiments on a single fuel cell was carried out. The experimental parameters included current collector shape, convection type and clamping force, respectively. The experimental results show that both the performances of the air-breathing and forced convection cells increase with an increase of the circle numbers from one to twenty-five on the current collector under the same current collector open ratio. The forced convection cell is a better choice for long-time high current-density output whereas the air-breathing cell is more suitable for lower current density output. An appropriate clamping torque should be considered carefully to enhance the performance but without narrowing down the fuel flow channels. The PDMS-based PEMFC has a better performance than that of the silicon-based one under both forced oxygen supply and the air-breathing ways; PDMS is a better material than silicon for micro air-breathing fuel cell because of its less water flooding effects.
