Structured catalysts and reactors for catalyst/reactor systems as a replacement for conventional fixed- bed reactors have recently attracted considerable attention, and microreactor systems based on a microchannel as a structured catalytic reactor have generated particular interest. The microreactor allows reactions that are difficult to realize using conventional fixed-bed reactors, and is also suitable for integration with the various additional components required for operation using microfabrication technologies. Small polymer electrolyte fuel cells (PEFCs), a promising clean and high-efficiency power source for portable electrical devices, require a reformer to produce hydrogen by the steam reforming of methanol. Such reformers typically have complex structures and have proven difficult to miniaturize. In this paper, a microreactor is proposed for use as a novel hydrogen producer for small PEFC systems.
