Abstract
A micro-scale catalytic combustor using high-precision ceramic tape-casting technology has been developed for high-temperature applications such as thermophotovoltaic power generation. Pd catalyst/nanoporous alumina support fabricated through anodic oxidation was employed for the catalyst layer. Combustor structure that gives much smaller temperature gradient with high fuel-conversion efficiency has been proposed based on a series of CFD analysis of heat and fluid flow and surface reaction. In combustion experiments with a prototype combustor, the wall temperature as high as 700℃ has been achieved. It is also found that the wall temperature gradient is significantly reduced with the present combustor structure.
