This 4th quarter report summarizes activity from July 1, 1995 through October 1, 1995; the report is organized as usual into sections describing background information and work performed under the main WBS categories: The Fuel Processor (WBS 1.0) team activity during this quarter focused on the continued design/development of the full scale fuel processing hardware. The combustor test stand has been completed allowing more detailed testing of the various parts of the combustor subsystem; this subsystem is currently being evaluated using the dual fuel (methanol/hydrogen) option to gain a better understanding of the control issues. The Fuel Cell Stack (WBS 2.0) team activity focused on material analysis and testing to determine the appropriate approach for the first GM stack. Five hundred hours of durability was achieved on a single cell fixture using coated titanium plates (anode and cathode) with no appreciable voltage degradation of the SEL (Stack Engineering Lab) produced MEA. Additionally, the voltage level drop across each of the plates remained low (<5mv) over the full test period; The system integration and control team focused on the initial layout and configuration of the system; and the Reference powertrain and commercialization studies are currently under review.
