Investigation on Generation Performance for Tubular Direct Methanol Fuel Cell

Abstract

Tubular cathode and plate anode were prepared by gel-casting process and coating process, which used mesocarbon microbead(MCMB) as raw materials, then cathode and anode were assembled to prepare single fuel cell. The generation performance for single tubular direct methanol fuel cell was tested under different electrolyte temperatures, methanol concentrations and oxygen flow rates, and the factors that affected the cell performance were discussed. The results showed that temperature and oxygen flow rate were the important factors of the generation performance in tubular direct methanol fuel cell (TDMFC), but the methanol concentration had a relatively smaller impact on the cell performance. The stability test of the cell after working for 100h shows that the tubular MCMB cathode had a perfect stability.
