摘要：

We designed a new type of high temperature proton exchange membrane (HT-PEM), which consists of polyethersulfone (PES)-Polyvinylpyrrolidone (PVP)-xSm(0.2)Ce(0.8)O(1.9) (SDC) (x = 0, 2 wt%, 4 wt%, 6 wt%), and the effect of SDC contents was systematically studied. The incorporation of SDC nanoparticles into the membrane plays a very important role in compromising the conductivity, the mechanical strength, and the durability of the membrane, because SDC has a certain extent proton conductivity, and the SDC has flocculent structure. The single cell shows the maximum power density of 1229 mW/cm(2) under a backpressure of 0.15 MPa at 160 degrees C, and the output performance keeps stable during the 1000 h stability test at a constant voltage of 0.7 V.
