A direct methanol fuel cell with an active area of 100 cm2 was tested experimentally under a variety of operating situations to determine its overall performance. Different operational parameters, such as anode flow rate (1–5 ml/min), cathode reactant (Air/Oxygen) and cathode flow rate (100–2000 ml/min) are the most influencing parameter, and the performance output of each parameter are compared. In addition, different cathode flow channels, such as serpentine and sinuous, are used to improve reactant supply, and their performance is compared with one another. Using sinuous flow field at the cathode and 3 ml/min of methanol and 500 ml/min of oxygen, the maximum power density of 24 mW/cm2 has been achieved.
