Abstract: | Microstructured reactors are being developed at IMM for the processing of various fuels to provide hydrogen for mobile and
portable fuel-cell systems. The key feature of the systems is the integrated-plate heat-exchanger technology, which allows
for thermal integration of several functions in a single device. For example, steam reforming may be coupled with exothermic
reactions in separate flow-paths of a heat exchanger. Catalyst coatings are also under development for numerous reactions,
such as propane steam reforming, methanol steam reforming, catalytic combustion, water-gas shift, and preferential oxidation
of carbon monoxide. These catalysts are being investigated in specially developed testing reactors. Reactors and complete
fuel processors are being tested up to 5 kW power output of the corresponding fuel cell.
This paper was presented at the ASM Materials Solutions Conference & Show held October 18–21, 2004 in Columbus, OH. |
