Mathematical Modeling of a DMFC Cathode with a Novel Structured MEA

摘要：

　　Membrane electrode assemblies (MEA) is the key component of a direct methanol fuel cell (DMFC) and its structure and fabrication technology influenced the performance of DMFC a lot.A novel structured MEA including a hydrophilic inner thin catalyst layer and a traditional outer catalyst layer,provide higher performance.To optimize the combination of the two catalysts layer a mathematical model based on Tafel type kinetics and semi-empirical mass transport coefficient was applied.The simulation of cathode overpotential results showed a DMFC with a 5μm thick inner Pt Blk catalyst layer and an 8μm thick outer 40wt%PtRu/C catalyst layer as cathode electrode was the best.
