甲醇重整气为燃料的质子交换膜燃料电池

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.
