A low-temperature co-fired ceramic micro-reactor system for high-efficiency on-site hydrogen production

Paul Muralt, Thomas Maeder, Bo Jiang, Dimos Poulikakos

A ceramic-based, meso-scale fuel processor for on-board production of syngas fuel was demonstrated for applications in micro-scale solid-oxide fuel cells (mu-SOFCs). The processor had a total dimension of 12 mm x 40 mm x 2 mm, the gas reforming micro react ...
