Optimization of hot pressing parameters in membrane electrode assembly fabrication by response surface method

► The MEA was prepared with porous electrodes with, a Nafion® 117 membrane and Pt and Pt/Ru. ► DOE work was performed with the RSM and the design applied was the CCD. ► Results show that the quadratic model can be used to obtain the operating conditions. ► By predicting the optimum performance of a passive micro DMFC.
