摘要：
Two one-dimensional, steady-state numerical models are presented to evaluate the performance of direct methanol fuel cells (DMFCs) in different aspects. One model is applied to simulate the double-layered catalyst structure, which reveals to greatly reduce both cathode and anode overpotential. Another model is created to simulate the effect of methanol and oxygen concentration on power density response in DMFC. In the numerical results, it was found that a DMFC consisting of double-catalyst layer electrodes exhibited many advantages over the traditional MEA, and the performances of the single cell are enhanced.
