|Presently, an important problem for low temperature polymer electrolyte fuel cells (PEMFCs) operating in the temperature range 50-100°C is the short time-life of proton conducting membranes. The present research work is thus focused on the development of single cell performances at low temperatures using alternative nonfluorinated hybrid proton exchange membrane based PVA polymer, which are chemically and mechanically more stable at low temperatures and Pt/C electrodes which can result into better fuel cell performance. The polarization profiles with the relationship between current density-potential (I–V) and the power densitycurrent density curves of the MEA consisting hybrid membrane and Pt/C catalyst analyzed at various humid conditions (50, 75 and 100% RH) with constant temperatures in the range from 40, 60, 80 and 90°C. The maximum current density of about 600 mA cm-2 was obtained at 90oC with 100% RH. We have compared these values with commercial Nafion® membrane and PVA based hybrid membrane electrolytes performed at low temperatures for H2/O2 fuel cells.|
