| 英文摘要 | clogging of anode flow channels by co2 bubbles is a vital problem for further performance improvements of the micro direct methanol fuel cell (mu dmfc). in this paper, a new type anode structure using the concept of the non-equipotent serpentine flow field (nesff) to solve this problem was designed, fabricated and tested. experiments comparing the mu dmfc with and without this type of anode flow field were implemented using a home-made test loop. results show that the mean-value, amplitude and frequency of the inlet-to-outlet pressure drops in the nesff is far lower than that in the traditional flow fields at high mu dmfc output current. furthermore, the sequential images of the co2 bubbles as well as the mu dmfc performance with different anode flow field pattern were also investigated, and the conclusions are in accordance with those derived from the pressure drop experiments. results of this study indicate that the non-equipotent design of the mu dmfc anode flow field can effectively mitigate the co2 clogging in the flow channels, and hence lead to a significant promotion of the mu dmfc performance. |
