热压制备低温固体氧化物燃料电池的初步研究

PRIMARY STUDY ON LOW TEMPERATURE SOLID OXIDE FUEL CELL FABRICATED BY HOT-PRESSING

引言固体氧化物燃料电池(Solid Oxide Fuel Cells,SOFC)由于具有能量转化效率高,不采用贵金属(如铂等)作催化剂,可直接使用碳氢燃料,易实现热-电联供或与燃气轮机组成联合循环系统,对环境友好。

The performance of low temperature solid oxide fuel cells fabricated by hot-pressing technology was studied at temperatures below 650℃. The cells consisted of Ce_(0.8)Sm_(0.2)O_(1.9)-salt (Li_2CO_3+Na_2CO_3) composite electrolyte, Ni anode, lithiated NiO cathode and Ni-net current collectors. For a reported cell here, the open-circuit voltages were 0.863 and 0.873 V, the measured maximum power densities were 0.615 and 0.743 mW~ cm^(-2) at 600 and 650℃, respectively. In the best case, the OCV of hot-pressed ...
