摘要：

Polymer electrolyte fuel cell stacks assembled with Johnson Matthey Fuel Cells and SolviCore MEAs based on the Aquivion (TM) short-side chain, chemically stabilized perfluorosulfonic acid membrane were investigated in the framework of the Autobrane EU project. Electrochemical experiments in fuel cell short stacks were performed under automotive conditions at pressures of 1-1.5 bar abs. over a wide temperature range, up to 130 degrees C, with varying levels of humidity (down to 18% R. H.). The stacks using the first set of large area (360 cm(2)) MEAs showed elevated performance in the temperature range from ambient to 100 degrees C (cell power density in the range of 600-700 mWcm(-2)) with a moderate decrease above 100 degrees C. The performances and electrical efficiencies achieved at 110 degrees C (cell power density of about 400 mWcm(-2) at an average cell voltage of about 0.6 V) are promising for automotive applications. Further optimization of membrane, MEAs and stack components to maximize the high temperature performance is currently underway.
