Abstract


The direct methanol fuel cell (DMFC) focused on the advantages of proton exchange membrane fuel cell is an important direction for future development of the fuel cell . Start two phase mass transfer direction from the DMFC porous electrode , the study focused on the processing within the flow channel . Different from the traditional view should be as efficient as possible was removed from the anode flow field has been injected improve the performance of fuel cells research in DMFC anode flow field . On this basis , the DMFC model is reasonable simplified physical model , to build a two - phase fluid flow bench and its mathematical model , a combination of experimental observations and theoretical analysis , draw the electrode inlet flow conditions on the porous seepage Finally , various effects , compared DMFC battery performance experimental results in the literature to verify the validity of the study , I hope to provide some reference for the design and improvement of DMFC .
