Abstract
Previous research shows that the performance of DMFC can be improved by applying the porous flow fields which can supply reactants evenly to the whole surface of electrodes compared to the operation with conventional straight groove flow field. This current paper describes the investigation on the performance of DMFC employing another porous flow fields made with sintered metal fiber which can also supply reactants evenly. The experiment results show that increasing the porosity of the new flow field decreases the reaction resistance due to the improved reactants supply and increasing the cell set bolt torque decreases the cell resistance.
