摘要：

This study was focused on the performances of membrane electrode assemblies (MEAs) consisting of the proton-conducting 90PVA/3PWA/4GPTMS/1P(2)O(5)/2Gl and 80PVA/10PWA/6GPTMS/2P(2)O(5)/2Gl hybrid membranes as electrolytes together with a Pt/C electrode for proton exchange membrane fuel cells. The MEAs were fabricated and tested as a function of temperature and humidity, and yielded a current density value of about 350 mA cm(-2) at 60 A degrees C and 100% relative humidity (RH) for the membrane electrolyte 80PVA/10PWA/6GPTMS/2P(2)O(5)/2Gl. These values were compared with NafionA (R) membranes, and the single-cell performances based on proton-conducting organic/inorganic hybrid electrolytes were discussed. The test conditions employed were equivalent for each MEA that had an active area of 5 cm(2). These hybrid membranes showed a high proton conductivity in the range of 10(-3)-10(-2) S cm(-1) at low temperatures, i.e., 60, 80, and 90 A degrees C, and 50%, 75%, and 100% RH.
