摘　　要：为降低燃料电池成本,促进国产燃料电池关键材料的广泛应用,利用国产石墨碳纸、国产全氟磺酸质子交换膜、国产Pt/C催化剂等燃料电池关键材料,采用基于固体电解质支撑催化层的工艺制备了膜电极多层组件。并组装了常压氢-空质子交换膜燃料电池,并对电性能进行了测试分析。通过对国产材料膜电极催化剂层载量、平整层载量以及制备工艺的优化,制备出了性能稳定的高性能国产材料膜电极。实验结果表明,在常压、操作温度为60℃、加湿温度50℃的条件下,国产材料H2-Air燃料电池的最高比功率可达到0.55W/cm2。实验表明,国产材料膜电极活性面积从5cm2增大到25cm2,电池在0.5V至开路区间的电性能几乎没有衰减,为大面积电堆的应用打下了坚实的基础。Key electrochemical materials are the most important factors for cost reduction and commercialization of proton exchange membrane fuel cell （PEMFC）. In this paper, domestic key materials for fuel cells including graphite fiber carbon paper, perfluorosulfonic acid proton exchange membrane and Pt/C catalyst were utilized to prepare membrane electrolyte assembly （MEA） based on catalyst-coating membrane （CCM） process. The fuel cell performances were tested in ambient pressure H2/Air fuel cell operation. With catalyst and sub-layer loading optimization and operation condition variation, reliable high performances were achieved. When operation temperature was 60 %; and the temperature after humidity was 50 %;, the power density of the fuel cell with domestic materials could be as great as 0.55 W/cm2 with ambient pressure hydrogen and air. With active area scale up from 5 cm^2 to 25 cm^2, no obvious performance reduction was observed.
