Abstract

Nowadays, the demand of higher energy density is crucial for high bandwith and advanced microprocessing electronic and wireless applications which the current technologies Li-ion and nickel based batteries no longer able to meet the requirement. Small fuel cells seems appealing solutions to the problem of providing portable energy sources. The direct ethanol fuel cell (DEFC) stacks are modular, simple to construct which attributes to compact and lightweight cell make it favorable for portable applications. Nevertheless, there are still many challenges for DEFC commercialization such as water transport management, EtOH crossover and the sluggish EOR kinetics on the anode. This complicated DEFC phenomena involved transport process, thermochemical reaction and fluids mechanisms which are hard to quantify by experiments. On the other hand, mathematical modeling is a powerful and economical tool, which enable us for better understanding the physical phenomena occurring during operation. The conceptual design was developed in this study to obtain power performance curve. The voltage and current characteristics with the proposed MEA geometry will be used as starting point for more detailed modeling and simulation studies aiming to provide basic understanding for the DEFC internal process. This study is to be used as initial estimations for engineers to design and optimize the DEFC performance for portable applications.
