Abstract

With the rapid development of micro-energy technology, passive micro-direct methanol fuel cell (P-μDMFC) has a promising application due to its high energy density, high efficiency, and merit of environmental protection. However, with the decrease of feature size an evident effect on internal gas–liquid two-phase transport appears. Besides, the water-management problems have a great influence on the performance of P-μDMFC because of microscale effects. Two major problems of the P-μDMFC are explained in detail in this chapter. One is the two-phase mass transfer problem at the anode, and the other is the water flooding problem at the cathode. The water management of a single P-μDMFC is also discussed from the perspectives of the water transport in the flow field channels, cathode catalyst layer, gas diffusion layer, and the membrane.
