Abstract

The dependence on fossil fuels as an energy source causes serious environmental problems. Direct ethanol proton exchange membrane fuel cells (DE-PEMFCs) that directly convert the chemical energy stored in the etanol alcohol into electricity makes it promising as an environment-friendly power source for portable and mobile applications. Increasing the reagent operating temperature increases the electrochemical kinetics at the anode, increasing the cell power. However in a DE-PEMFC, the flow field plate directly interferes at the heat flow. As a result, the aim of this research were project a new parallel serpentine flow field plate with interdigitated characteristics, a parallel serpentine-baffle flow field plate (PSBFFP) and comparing with a PSFFP with respect to heat transfer performance in a DE-PEMFC anode side. The results show that the discontinue channels presents in the PSBFFP improve the heat transfer between plate and reagent, improving the reaction rate and consequently the fuel cell performance.
