The 5kW integrated system has been fully assembled and successful checks were made of most microprocessor-controlled operational features. Long-term testing will be deferred until the stack is rebuilt. A PURPA-derived definition of qualified cogenerator has been supplied by A.D. Little, Inc. Preliminary considerations are presented for the designs of the 25 kW stack and the 50 kW methanol fuel processor. Initial results are given for overall system analysis of a 50kW system under pressurized operation and also under part-load operation at normal pressure. A general discussion of waste heat utilization is also provided. Progress in several areas of stack componentry is reported, including bipolar plate production, acid management, Pt catalyst recrystallization and bipolar plate resistance measurement technique. Methanol steam reforming catalyst test results are reviewed in preparation for making a choice of design catalyst for the 50 kW system.
