Start-up characteristics of commercial propane steam reformer for 200 We portable fuel cell system

Electrical start-up for diesel fuel processing in a fuel-cell-based auxiliary power unit

“…This approach implements the findings in [14], according to which it is much faster to heat HT-PEFC stacks with hot air than with electrical heaters. In addition, a modified method of reactive heating, which was identified as promising for start-up in the literature [2,3,7,12], was adopted for the start-up procedure here. The result is a hybrid start-up procedure for the complete system.…”

“…A resistance heater was embedded inside the catalytic reactor bed and was activated until the exothermic oxidative reaction was ignited. Lee et al [7] optimized the start-up characteristics of a commercial propane steam reformer for a portable fuel cell system. They extended the start-up strategy based on external heating using the spark ignition of the catalytic combustor by introducing a slip stream of air into the reformate line at the inlet of the WGS reactor.…”

Purification of H<inf>2</inf>-rich gas from methanol reformer by preferential oxidation over Pt-Ru/Al<inf>2</inf>O<inf>3</inf> catalyst

“…Pt supported on Ce-modified TiO 2 showed better activity than those corresponding to individual ceria and titania supported catalysts. Additionally, the Ce-TiO 2 supported catalyst illustrated better stability at reaction temperatures higher than 573 K. Lee et al [7] designed a propane reforming system introduced a stream of air into the upstream of the water gas shifting reactor. The air feed to preheat the WGS reactor in the start-up period could reduce CO levels less than 50 ppm detected in outlet of PrOX reactor.…”
