A numerical and experimental investigation of an ammonia-fuelled microchannel processor for hydrogen generation.

Ammonia decomposition was assessed as a fuel processing technology for producing hydrogen on-demand for fuel cell applications. An experimental study of an ammonia-fuelled microchanel reactor was undertaken, and the performance data subsequently used to develop and validate a mathematical model for the effective design of microchannel reactors for ammonia decomposition. The work described in the thesis was motivated by the need for a convenient and efficient method of providing hydrogen for a proton-exchange membrane fuel cell (PEMFC) in portable and distributed power applications.
