Major conclusions from the on-site system application analysis (Arthur D. Little, Inc.) are summarized. OS/IES internal rates of return (IRR) are relatively attractive when the fuel cell system is designed for the base-load, rather than for the average-load, and when operated on natural gas, rather than on methanol. For this grid-connected system, electric utility rate structures are more important in determining IRR than building loads and climate. High demand for hot water has been identified as an important consideration in matching the energy capabilities of the OS/IES to the site. Building types that will be analyzed extensively are hospitals, offices, apartments, and retail stores. Preparations have been completed for the first test of a full-sized single-cell (0.33 m x 0.56 m). Emphasis of the methanol fuel processor development program has shifted toward the use of commercial shell-and-tube heat exchangers. An improved method for predicting the carbon-monoxide tolerance of anode catalysts is described. This is a cyclic-voltametric test and correlates well with the results of much more time-consuming single-cell testing. Other stack support areas reported on include improved ABA bipolar plate bonding technology, improved electrical measurement techniques for specification-testing of stack components, and anodic corrosion behavior of carbon materials. The conclusion of endurance testing of the thermally stable and ethanol-resistant C70-2RS methanol-reforming catalyst is presented and results are compared to those obtained earlier on T2107RS catalyst.
