| 摘 要： | 进行了甲醇重整气与燃料电池的联合试验。与PEMFC配套的甲醇制氢氢源系统运行稳定，出口氢浓度为43-45%，CO含量为0-6ppm，压力控制在0.22~0.25MPa(表压)。单对电池氢的利用率可达到83%，电池排氢浓度为12%以下。不同氢源下PEMFC性能从高到底的顺序为纯氢、甲醇重整气、配气。单电池试验表明，微量的甲醇或二甲醚对电池未发现明显的影响。

| Abstract: | In this work, methanol reforming and methanol reformate gas coupled with a proton exchange membrane fuel cell （PEMFC）were investigated.The results of the methanol reforming system showed that the system worked stably.The H2 concentration at the outlet was 43%～45%, CO concentration was 0—6×10-6, and the system pressure was 0.22—0.25 MPa(gage).The H2 utility of a single PEMFC was 83%, and the H2 emission concentration of the fuel cell was lower than 12%.The PEMFC power was strongly influenced by the purity of H2, particularly in the presence of CO.The PEMFC performance showed a reduction trend in the order of pure H2, reformate gas and mixture gases.A small amount of CH3OH or (CH3)2O had no apparent effect on the performance of the single fuel cell.. |
