Catalyst-coated membrane (CCM) and catalyzed diffusion medium (CDM) prepared either by brush painting method or by spraying method were compared for direct methanol fuel cell (DMFC) anode and cathode. The pore structure and the morphology of the electrodes were characterized by mercury intrusion porosimetry (MIP) and scanning electron microscopy (SEM). Internal resistance corrected polarization curves...
A Pd layer was deposited on Nafion ® membrane by electroless plating in order to reduce methanol crossover. The composite membrane was characterized by using the following techniques of X-ray diffraction (XRD), scanning electron microscope (SEM), energy dispersive X-ray spectrometer (EDXS) and transmission electron microscopy (TEM). Methanol crossover was determined by the electrochemical...
