The use of alternative fuels can provide clean energy supply chains with low greenhouse gas emissions and pollutants. The conversion of the chemical energy of these fuels, such as methanol, into electrical energy is an important link in this chain. Direct methanol fuel cells (DMFCs) are devices that can produce, through electrochemical reactions, electrical energy from the chemical energy contained in methanol and oxygen. Currently, these devices have lower efficiency and power density compared to hydrogen fuel cells, so the improvement of these devices becomes essential for their possible large-scale use. The power density of DMFCs can be increased by controlling parameters such as temperature, concentration and flow rate of the methanol supplied. In this work, the combination of these parameters that improves the performance of these devices is obtained by applying the Response Surface Methodology (RSM).
