【 摘 要 】

In this study, a three-dimensional numerical model has been established and validated for microfluidic fuel cell (MFC) with flow-through porous electrodes. Systematically parametric analyses are performed to evaluate the effects of electrode aspect ratio on the reaction rate distribution in this energy system. Based on the results, the feasibility of improving the utilization degree of the porous electrode by alternating the electrode aspect ratio is demonstrated and optimized electrode aspect ratio is derived for this energy system.
