Abstract : The fuel cell program has made progress in four key areas including (1) fabrication and testing of membrane electrode assemblies (MEAs), (2) fundamental studies of methanol oxidation on smooth alloy electrodes, (3) half cell studies of membrane electrode assemblies and (4) X-ray studies of anode catalytic materials. Two fuel cell test stands with computerized data acquisition systems are now fully operational. We have fabricated MEAs with hydrogen/oxygen performance curves competitive with state-of-the-art electrodes. In addition, studies of Pd barrier electrodes have been initiated and currents of 400 mA/sq cm at 0.5 volts are typical with hydrogen/methanol-oxygen. We have now terminated the hydrogen/methanol blend experiments and are now focusing on liquid methanol/water feed. We are currently struggling with the methanol delivery system and development of macroporous electrodes for methanol. Since the time of this report, IIT and Argonne National Laboratory have made one visit to the synchrotron at Brookhaven National Laboratory. Data analysis is in progress. jg
