Proton Exchange Membrane Fuel Cells (PEMFC) are competitive and sustainable energy-conversion devices and show promise to replace petrolic power sources. Especially, the PEMFC electrodes consist of the catalyst and the Nafion binder, which present low dispersibility in the pure solvents, leading to the low electrode utilization. To overcome such limitations, it is necessary to improve understanding of the influence of the catalyst ink on the PEMFC performance. In this study, the effect of solvent for the catalyst ink on the fuel cell performance was investigated in terms of the catalyst layer (CL) morphology. The impedance spectra of the CLs were obtained to thoroughly explore the relation between the CL structure and the cell polarization. |
